Contributor: Meghan Hurley, MD Educational Pearls: What is hyperkalemia? Hyperkalemia is when the measured blood level of potassium reaches above 5.2 - 5.5 mEq/L (normal 3.5 - 5.2 mEq/L). What are common causes of hyperkalemia? Chronic or acute kidney disease. Medications that impact the Renin-Angiotensin-Aldosterone-System (RAAS). Hypoaldosteronism and primary adrenal insufficiency (Addison's Disease). What are concerns of hyperkalemia? The biggest concern with hyperkalemia is the impact on the cardiac conduction system. At differing levels of hyperkalemia, the patient may initially have peaked T waves, that then progress into a widening of the QRS complex which may eventually lead to a sine wave pattern. This increases risk for cardiac arrest with ventricular fibrillation, PEA, and asystole. What is the treatment algorithm for hyperkalemia? Works through a three-tier approach. First tier treatment is with a calcium agent (calcium gluconate or chloride). Thought for the longest time to "stabilize the cardiac membrane/action potential". Recent research shows the true mechanism of action is likely through acting on calcium dependent channels. Does not fix underlying hyperkalemia, but buys time for the heart. Second tier treatment is inducing intracellular potassium shift. Can be achieved through agents such as insulin (which may need to be bolused with glucose to prevent hypoglycemia), albuterol, or sodium bicarbonate. Third tier is potassium elimination If the patient is producing urine, loop or thiazide diuretics can be considered. Hemodialysis may also be considered based on patient condition. Long term (and slowest method of elimination) through fecal excretion. Unlikely to see benefits in emergency management. Key Takeaways? Hyperkalemia is a condition that can be brought on by primarily renal conditions and medication side effects. Careful attention must be paid to the patient's cardiac status, and urgent cardiac stabilization (though now we may know that calcium doesn't truly "stabilize" the cardiac membrane) must be performed to prevent deadly arrhythmias. Definitive management involves addressing the offending agent, offloading potassium, and stabilizing the patient long term. References: Geldermann N, Dzimiera J, Fischer H, Christ M.

Picture this. You're standing over a patient whose monitor is showing one of the most frightening rhythms in cardiology. Someone says, "It's complete heart block," and suddenly everyone's focused on the ECG. But here's the question that separates a technician from a clinician: Do you actually understand why it's happening? In this episode of Ten Minute Medic, we're going beyond memorizing P waves, QRS complexes, and AV dissociation. Instead, we're going to pull back the curtain on the heart's electrical system and discover why third-degree heart block is actually one of the most logical rhythms in medicine. Once you understand the physiology, you'll never have to memorize this rhythm again—you'll be able to predict it, explain it, and, most importantly, recognize what it means for your patient. So, if you're ready to stop chasing rhythm strips and start understanding the story they're telling, let's jump in. Third Degree Heart Block Study Guide
CardioNerds (Drs. Apoorva Gangavelli, Jenna Skowronski, and Hannah Every) discuss the continuum of prevention and heart failure with Drs. Anu Lala and Martha Gulati. Grounded in a clinical case of a 55-year-old woman with uncontrolled hypertension, type 2 diabetes, and obesity who is on the trajectory toward heart failure, this episode unpacks a paradigm-shifting framework from a joint HFSA/ASPC Scientific Statement. The discussion explores how prevention should not be siloed from heart failure management but rather integrated across a patient’s lifespan—from primary prevention in at-risk individuals, to secondary prevention in those with established heart failure, to tertiary prevention in patients with advanced therapies such as LVADs and heart transplantation. The experts highlight the importance of aggressive risk factor management, biomarker-guided screening, the AHA’s Life’s Essential 8, and the need for multidisciplinary collaboration and systems-level change to shift heart failure care from reactive to proactive.

Pearls Systemic inflammatory diseases are associated with an elevated CVD risk that has significant implications for early detection, risk Heart failure prevention is a continuum, not a checkpoint. Prevention applies at every stage—from at-risk (Stage A) through advanced/post-transplant care—and every clinical encounter is an opportunity to intervene. The AHA’s Life’s Essential 8 (diet, physical activity, nicotine exposure, sleep, BMI, blood lipids, blood glucose, blood pressure) forms the foundation at every stage. Hypertension carries the highest population-attributable risk for heart failure of any modifiable risk factor. In the Framingham Heart Study, 91% of patients with newly diagnosed HF had pre-existing hypertension. The SPRINT trial demonstrated a 38% reduction in HF incidence with intensive blood pressure targets (30 ng/L or NT-proBNP >125 ng/L) identify individuals at heightened risk for progression to symptomatic HF. The ACC/AHA/HFSA guidelines give a Class IIa recommendation for natriuretic peptide screening in at-risk patients. Urine albumin-to-creatinine ratio (UACR) is an underutilized screening tool that provides additional insight into CKM risk. The heart failure label does not close the prevention window—it accentuates it. Secondary prevention through GDMT optimization (quadruple therapy in HFrEF) and continued risk factor management remains critical. Tertiary prevention extends to post-LVAD and post-transplant patients, where hypertension, diabetes, obesity, and CKD management remain essential to long-term outcomes. Show notes For a comprehensive review, please review the full HFSA/ASPC Joint Scientific Statement: Lala A, Beavers C, Blumer V, et al. The Continuum of Prevention and Heart Failure in Cardiovascular Medicine. J Card Fail. 2026;32:75-105. doi:10.1016/j.cardfail.2025.06.013 1. What is the “continuum of prevention” framework, and how does it differ from traditional approaches to heart failure prevention? Historically, prevention and heart failure management have been treated as separate disciplines—primary prevention handled by preventive cardiologists and treatment managed by heart failure specialists. This joint HFSA/ASPC Scientific Statement reframes prevention as a dynamic, continuous process that spans a patient’s entire lifespan, regardless of HF stage or ejection fraction. The framework maps onto the ACC/AHA HF staging system: Primary prevention targets Stage A (“at risk”) and Stage B (“pre-HF”) patients to reduce the burden of incident HF. Secondary prevention targets Stage C (symptomatic) and Stage D (advanced) patients to reduce the impact of established HF through GDMT optimization and ongoing risk factor management. Tertiary prevention encompasses risk factor management in patients with LVADs or heart transplants—populations where hypertension, diabetes, and obesity still drive outcomes. The Central Figure of the statement illustrates that Life’s Essential 8 (blood pressure and lipid control, diabetes management, exercise, sleep, smoking cessation, weight management, and diet/nutrition counseling) forms the foundation at every stage, with pharmacologic and device-based therapies layered on top as disease progresses (Figure) 2. How do traditional risk factors drive heart failure, and what should clinicians prioritize? Hypertension carries the greatest population-attributable risk for HF. In the Framingham Heart Study (N=5,143), HTN was associated with a 2- to 3-fold increased risk of HF, with a population-attributable risk of 39% in men and 59% in women. The SPRINT trial showed a 38% reduction in HF incidence and 25% reduction in the primary composite outcome with intensive BP targets (30 ng/L or NT-proBNP >125 ng/L) are associated with heightened risk for progression to symptomatic HF. In the ARIC study, incorporating NT-proBNP reclassified 20% of older adults without HF into Stage B. Factors that affect interpretation include age, sex, obesity (lower values), and CKD (higher values). High-sensitivity cardiac troponin (hs-cTn): Concentrations above the 99th percentile are now included in the definition of Stage B HF. Troponin testing may complement natriuretic peptides, particularly when BNP/NT-proBNP values are ambiguous. Risk scores: The PCP-HF equation predicts 10-year HF risk using traditional risk factors plus QRS duration. The AHA PREVENT score incorporates HF risk calculation and includes markers of kidney function (albuminuria, eGFR), though it may underestimate risk in men and Black adults. The CKM syndrome staging framework (Stages 0–4) provides a holistic approach to assessing systemic cardiovascular-kidney-metabolic risk. 4. What are the key nontraditional risk factors and cross-cutting themes in heart failure prevention? Genetics: Pathogenic cardiomyopathy variants exist in ~1 in 200 individuals in the general population. The HFSA and ACMG recommend cascade testing to identify at-risk family members. Polygenic risk scores for dilated cardiomyopathy show a 3.8-fold risk for DCM in the top 10th percentile compared with the median. Sex-specific considerations: Women have 2.8 times the odds of developing HFpEF, while men have similarly increased odds of HFrEF. A complete obstetric/gynecologic history is essential—preeclampsia is associated with a 4-fold increased risk of HF. Peripartum cardiomyopathy requires intentional screening in high-risk populations. Cardiotoxic exposures: Clinicians should be aware of medications that cause direct myocardial toxicity (e.g., anthracyclines, trastuzumab, tyrosine kinase inhibitors). A team-based approach with pharmacists can help optimize medication selection and risk factor modification. Social determinants of health: Environmental exposures (air pollution, arsenic, lead, cadmium), food insecurity, financial instability, and limited healthcare access contribute to HF risk and progression. Equity-focused, risk-based prevention strategies are needed. Psychological health: Depression is common in HF and independently associated with worse outcomes. Screening with brief questionnaires (e.g., PHQ-2) is recommended. Meditation, spirituality, and holistic wellness approaches remain underutilized. 5. What systems-level and policy changes are needed to move the needle on heart failure prevention? Multidisciplinary HF prevention clinics that bring together preventive cardiologists, HF specialists, endocrinologists, nephrologists, dietitians, pharmacists, exercise physiologists, and genetic counselors are advocated by the statement. EHR-embedded risk stratification could proactively flag patients on a trajectory toward HF—analogous to sepsis alerts or fall risk flags—enabling earlier intervention, particularly for patients who may not reach a cardiologist. Cardiac rehabilitation remains underutilized, particularly in HFrEF (Class 2b recommendation) and HFpEF (not yet covered by Medicare). The HF-ACTION trial showed quality-of-life benefits, and the REHAB-HF trial showed particular benefit in older patients with HFpEF. Policy priorities include expanding insurance coverage for preventive screening and novel therapies (SGLT2i, GLP-1 RAs, nsMRAs), reducing clinical inertia through team-based care models with closer follow-up intervals, and ensuring equitable access to evidence-based therapies across diverse populations. Digital health and AI hold promise for personalized risk prediction, remote monitoring (e.g., wearable devices, implantable PA pressure monitors), and virtual cardiac rehabilitation to overcome access barriers.

Audio editing by CardioNerds academy intern, Grace Qiu. The International Collaborative LBBAP Study (I-CLAS) evaluated clinical outcomes between biventricular pacing (BVP) and left bundle branch area pacing (LBBAP) in patients with left ventricular ejection fraction (LVEF) ≤50% undergoing cardiac resynchronization therapy. Between January 2018 and June 2023, 2,579 patients were enrolled across 18 centers. The primary composite outcome was defined as all-cause mortality or heart failure hospitalization. LBBAP demonstrated a shorter paced QRS duration and was associated with a lower risk of primary composite outcome and heart failure hospitalization. No significant difference was observed in all-cause mortality. Additionally, procedural complications were lower with LBBAP. This episode was planned in collaboration with Heart Rhythm TV with mentorship from Dr. Daniel Alyesh and Dr. Mehak Dhande.

We discuss this ominous complication of providing local anesthesia. Hosts: Elaine Jonas, MD Brian Gilberti, MD https://media.blubrry.com/coreem/content.blubrry.com/coreem/LAST.mp3 Download Leave a Comment Tags: Critical Care, Toxicology Show Notes I. Pathophysiology & Mechanisms Definition: Systemic toxicity secondary to local anesthetic (LA) via accidental intravascular injection or excessive systemic absorption. Threshold: Occurs when plasma concentration exceeds the safety threshold for cardiac and neural tissue. Agent Profile: Bupivacaine (High Risk) Highly lipophilic with high protein binding. “Fast-on, Slow-off” Kinetics: Strong Na+ channel binding with extremely slow dissociation during diastole. Myocardial Depression: Direct inhibition of Ca2+ release from the sarcoplasmic reticulum, impairing contractility. Low CC:CNS Ratio: The dose required for cardiac collapse is very close to the dose that triggers seizures (narrow safety margin). Contributing Factors: Acidosis/Hypercapnia: Increases the fraction of free drug and promotes ion trapping in the brain/heart; shifts the LA-binding curve toward higher toxicity. Hypoxemia: Exacerbates myocardial depression and lowers seizure threshold. II. Risk Assessment & Prevention Patient-Specific Risk Factors Extremes of Age: Neonates (low α-1-acid glycoprotein) and elderly (reduced clearance). Body Composition: Low muscle mass/frailty (decreased volume of distribution). Organ Dysfunction: Hepatic: Reduced metabolism of amide LAs. Renal: Accumulation of metabolites; risk of metabolic acidosis lowering seizure threshold. Cardiac: Reduced cardiac output slows hepatic delivery/clearance; heart failure patients are more sensitive to Na+ channel blockade. Pregnancy: Increased sensitivity to cardiotoxicity. Procedural Risk Factors Vascularity of Site (Highest to Lowest Risk): Intercostal blocks (highest absorption rate). Caudal/Epidural. Interfascial plane blocks (e.g., TAP block). Psoas compartment/Sciatic. Brachial plexus. Technique: Large volume infiltration, lack of ultrasound, lack of incremental injection. Prevention Mandates Weight-Based Dosing: Lidocaine (Plain): Max 4.5 mg/kg. Lidocaine (with Epi): Max 7 mg/kg. Bupivacaine: Max 2.5–3 mg/kg. Incremental Injection: 3–5 mL aliquots with frequent aspiration. Intravascular Marker: Use Epinephrine (1:200,000) to detect accidental IV placement (HR increase >10 bpmor SBP increase >15 mmHg). III. Clinical Presentation Neurologic Phase (Early to Late) Subjective: Metallic taste, tinnitus, circumoral numbness/tingling. Objective: Visual disturbances, agitation, confusion, tremors. Critical: Generalized tonic-clonic seizures, rapid progression to CNS depression, coma, and apnea. Note: Early phases are often masked in patients receiving midazolam or propofol. Cardiovascular Phase Initial: Hypertension and tachycardia (if epi used) or transient stimulatory phase. Conduction Defects: PR prolongation, QRS widening (classic sign), bundle branch blocks. Dysrhythmias: Bradycardia (most common), VT/VF, PEA, asystole. Contractility: Profound, refractory hypotension and cardiogenic shock. IV. Immediate Management Algorithm Goal: Prevent hypoxia/acidosis and sequester the toxin. 1. Initial Actions Stop Injection: Immediately halt all LA administration. Call for Help: Specify “LAST Protocol” and “Intralipid Kit.” Airway Management: 100% O2. Hyperventilate slightly if needed to counter respiratory acidosis. Low threshold for intubation (hypoxia/acidosis rapidly worsen LAST). 2. Seizure Control First-line: Benzodiazepines (e.g., Midazolam). Avoid: Propofol if hemodynamically unstable (exacerbates cardiac depression). Neuromuscular Blockers: May be needed for ventilation, but remember they do not stop CNS seizure activity. 3. Lipid Emulsion Therapy 20% Indications: Start at first sign of serious toxicity (airway compromise, seizures, or CV instability). Bolus: 1.5 mL/kg IV over 1 minute. Infusion: 0.25 mL/kg/min immediately following bolus. If Instability Persists: Repeat bolus (up to 2 times). Increase infusion to 0.5 mL/kg/min. Upper Limit: ≈12 mL/kg total dose. 4. Modified ACLS Epinephrine: Use low doses (

Wil sits down in-person with Tim McLaughlin, technologist-turned-operator who founded GoTab after opening two Caboose breweries and confronting real service-model pain (giant spaces, staffing constraints). Years before COVID, Tim taped QRs to tables and proved guests will change behavior to avoid pain (lines), which pushed GoTab to build not just ordering but a deep KDS and, later, a POS when closed ecosystems (e.g., API roadblocks) blocked integrations. Today GoTab focuses on operations over payments, hybrid service (QR + handheld + kiosk), open integrations, and white-glove 24/7 support, while running lean and profitable (not “growth at any cost”). With Opsie for inventory/costing, expansion in higher-labor markets like Australia, and an operator-first pricing philosophy (inspired by Costco's cap idea), Tim argues tech should feel invisible, amplify hospitality, and never replace it.10 Takeaways Pain drives adoption: guests embraced QR ordering in 2018 at Caboose Commons to skip long lines—two years before COVID. Operations > payments: GoTab's edge is the KDS/factory-mindset—batching, throttling, inventory links—not just taking money. Hybrid service wins: seamlessly mix QR tabs, handheld orders, kiosks, and traditional POS—flip zones on/off in real time. Open…for real: GoTab publishes APIs and keeps integrations (even with competitors to Opsie) because operators need choice. Closed ecosystems cost you: API fees/blocks pushed GoTab to build its own POS so operators aren't held hostage. Service is strategy: 24/7 phone/text/chat, humans + AI, fast responses—because hospitality vendors must model hospitality. Lean and profitable: modest capital, disciplined hardware R&D, profitable growth > headline valuations. Inventory is the sleeper win: most independents skip it; Opsie aims for “no-effort” inventory & COGS visibility inside GoTab. Follow labor costs: higher-labor markets (e.g., Australia with double-time on holidays) adopt efficiency tech faster. Pricing with trust: exploring a Costco-style profit cap; focus on transparent value, not nickel-and-diming via fees.

Modeling Disease Pathways Through Ventricular Depolarization Guest: Peter van Dam, PhD Host: Anthony H. Kashou, MD Detection of disease progression is hampered due to the large variation in normal QRS morphologies, even for the ECG expert. Cardiac modeling techniques can improve the interpretation and diagnostic value of the ECG by visualizing relevant QRS deviations. Comparing the QRS waveforms and electrical pathway in genetical patients to normal controls shows that even small changes in the QRS can be detected in patients with a genetical disease, like Brugada or ACM. Topics Discussed: What is the PathECG? How do you compare PathECG to normal ECG waveform? What can the PathECG add to the ECG? Could PathECG improve the quality of the ECG diagnosis?

Contributor: Travis Barlock MD Educational Pearls: What is the ST segment? The ST segment on an ECG represents the interval between the end of ventricular depolarization (QRS) and the beginning of ventricular repolarization (T-wave). It should appear isoelectric (flat) in a normal ECG. What if the ST segment is elevated? This is evidence that there is an injury that goes all the way through the muscular wall of the heart (transmural) This is very concerning for a heart attack (STEMI) but can be occasionally caused by other pathology, such as pericarditis What if the ST segment is depressed? This is evidence that only the innermost part of the muscular wall of the heart is becoming ischemic This has a much broader differential and includes a partial occlusion of a coronary artery but also any other stress on the body that could cause a supply-and-demand mismatch between the oxygen the coronaries can deliver and the oxygen the heart needs This is called subendocardial ischemia What else should you look for in the ECG to identify subendocardial ischemia? The ST-depressions should be at least 1 mm The ST depressions should be present in leads I, II, V4-6 and a variable number of additional leads. There is often reciprocal ST elevation in aVR > 1 mm The most important thing to remember when you see subendocardial ischemia is…history Still, keep all cardiac causes on your differential, such as unstable angina, stable angina, Prinzmetal angina, etc. Also consider a wide array of non-cardiac causes such as severe anemia, severe hypertension, pulmonary embolism, COPD, severe pneumonia, sepsis, shock, thyrotoxicosis, stimulant use, DKA, or any other state that lead to reduced oxygen supply to the subendocardium and/or increased myocardial oxygen demand.

Question #37 Mr. S is an 80-year-old man with a history of hypertension, type II diabetes mellitus, and hypothyroidism who had an anterior myocardial infarction (MI) treated with a drug-eluting stent to the left anterior descending artery (LAD) 45 days ago. His course was complicated by a new LVEF reduction to 30%, and left bundle branch block (LBBB) with QRS duration of 152 ms in normal sinus rhythm. He reports he is feeling well and is able to enjoy gardening without symptoms, though he experiences dyspnea while walking to his bedroom on the second floor of his house. Repeat TTE shows persistent LVEF of 30% despite initiation of goal-directed medical therapy (GDMT). What is the best next step in his management?AMonitor for LVEF improvement for a total of 60 days prior to further interventionBImplantation of a dual-chamber ICDCImplantation of a CRT-DDContinue current management as device implantation is contraindicated given his advanced age Answer #37 Explanation Choice C is correct. Implantation of a CRT-D is the best next step. In patients with nonischemic DCM or ischemic heart disease at least 40 days post-MI with LVEF ≤35% and NYHA class II or III symptoms on chronic GDMT, who have reasonable expectation of meaningful survival for >1 year,ICD therapy is recommended for primary prevention of SCD to reduce total mortality (Class 1, LOE A). A transvenous ICD provides high economic value in this setting, particularly when a patient's risk of death from ventricular arrhythmia is deemed high and the risk of nonarrhythmic death is deemed low. In addition, for patients who have LVEF ≤35%, sinus rhythm, left bundle branch block (LBBB) with a QRS duration ≥150 ms, and NYHA class II, III, orambulatory IV symptoms on GDMT, cardiac resynchronization therapy (CRT) is indicated to reduce total mortality, reduce hospitalizations, and improve symptoms and QOL. Cardiac resynchronization provides high economic value in this setting. Mr.

CardioNerds (Drs. Teodora Donisan, Jenna Skowronski, and Johnny Hourmozdi) discuss Cardiomyopathies with Dr. Steve Ommen. Through a case-based discussion, we review the diagnostic evaluation of suspected restrictive cardiomyopathy, and Dr. Ommen shares his expertise in the nuances of caring for patients with hypertrophic cardiomyopathy, from counseling to pharmacologic, device, and septal reduction therapies. We cover the foundations of diagnosis and management that will be helpful to CardioNerds preparing to encounter hypertrophic cardiomyopathy on the boards or on the wards. Dr. Johnny Hourmozdi drafted notes. The audio was engineered by Dr. Atefeh Ghorbanzadeh. The CardioNerds Beyond the Boards Series was inspired by the Mayo Clinic Cardiovascular Board Review Course and designed in collaboration with the course directors Dr. Amy Pollak, Dr. Jeffrey Geske, and Dr. Michael Cullen.

Pearls and Quotes - Cardiomyopathies The presence of an S4 and a rapid y-descent in the jugular venous pulsation on exam should clue you to the presence of a restrictive filling pattern. Restrictive filling doesn't necessarily mean restrictive cardiomyopathy and is more commonly due to dilated or ischemic cardiomyopathy. The five main topics of counseling that every hypertrophic cardiomyopathy (HCM) patient should understand: (1) Prognosis, (2) Family Screening, (3) Risk of Sudden Death, (4) Treatments, and (5) Physical Activity. Remember 1/3: In clinical trials of cardiac myosin inhibitors for HCM (mavacamten), about a third of patients had a tremendous improvement in symptoms, another third had some improvement, and the final third had no improvement or had to discontinue the drug due to negative inotropy. When counseling patients about septal reduction therapy, consider the patient's age. For younger patients, surgical myectomy at an experienced center offers a higher success rate and greater durability with lower rates of pacemaker placement when compared to alcohol septal ablation. Historically, the conclusion that it was higher risk to be an athlete with HCM was unfortunately generalized to mean that it was high risk to exercise for patients with HCM. “And we turned a generation of HCM patients into HCM cardiometabolic syndrome patients, which is actually a worse combination.” Notes - Cardiomyopathies What is the initial approach to evaluating a patient with new or suspected cardiomyopathy, including hypertrophic cardiomyopathy (HCM)? A history and physical exam, including a thorough past medical and family history, is always the first step and helps determine the patient's risk for potential underlying etiologies, including genetic cardiomyopathies, hypertrophic cardiomyopathy, or those related to treatments of previous cancer. In terms of ECG findings, pay attention to QRS voltage (high or low) and the presence of any arrhythmias. TTE should be obtained in all patients and is often sufficient to diagnose many underlying cardiomyopathies, including HCM. Cardiac MRI (CMR) is helpful as an adjunct when TTE alone is inconclusive or imaging quality is poor. CMR can help provide a better idea of chamber sizes and wall thickness, and late gadolinium contrast enhancement (LGE) can also be helpful if present in a specific pattern, though often HCM patients may have non-specific patterns of LGE. Invasive hemodynamics assessment is reserved for patients with discordance between non-invasive testing and the clinical impression. It can also be useful to guide the management of heart failure, especially in advanced disease. How do you treat patients with hypertrophic obstructive cardiomyopathy (HOCM)? In patients with HCM and LVOT obstruction (defined a...

Understanding ECG Waveforms: Normal vs. Abnormal Guest: Dr. Peter van Dam Host: Anthony H. Kashou, M.D. The ECG interpretation is majorly driven by event detection, i.e. QRS onset and end, QT time, P wave etc. From these we can determine the normal heart rhythm, and some performance measures, like heart rate etc. The ECG waveforms, however, are much less understood. This is a pity, as ECG waveforms, provide instantaneous information on the electrophysiological and structural function of the heart. In this respect it is interesting to know if there is something like a normal ECG waveform or normal PathECG (CineECG). This latter technique is a vector-based method to estimate the electrical position of a moving vector within the heart. Similar normal distributions can be created to compare to the normal ECGs. Topics Discussed How can we define a normal ECG waveform? (ECGs from healthy normal people for different age groups, I used about 6000 normal ECGs, correction for heart rate by resampling to standard QT time (400 ms for instance, these ECGs can be used to create a distribution of amplitudes and derived signals (CineECG) to compare an ECG too) What is needed for an accurate waveform comparison? (Good baseline correction, not filtering, but baseline correction) What is the onset and end of the P-wave, QRS and T wave?) Are normal ECGs waveforms different from abnormal ECG waveforms? (Of course they overlap, describe left bundle branch block, or ischemia, with long QRS or deviating ST segment ) Did you use this method to classify ECGs as normal or abnormal? (results from our study (manuscript in preparation) that any QRST sequence in an ECG can be classified as abnormal with an accuracy (AUC) of more than 81%. In our study population 15% of the patients had only atrial related abnormal ECGS) Connect with Mayo Clinic's Cardiovascular Continuing Medical Education online at https://cveducation.mayo.edu or on Twitter @MayoClinicCV and @MayoCVservices.

Deepthy Varghese, MSN, ACNP, FNP, Northside Hospital is joined by James O'Hara, PhD, PA, Virginia Heart, and Shunmuga Sundaram Ponnusamy, MBBS, MD, CEPS-A, Velammal Medical College Hospital, and Research Institute to discuss a study that evaluated the impact of QRS morphology on the risk of life-threatening ventricular arrhythmias in heart failure patients treated with cardiac resynchronization therapy with a defibrillator (CRT-D). The analysis included 2,862 patients from five major ICD trials, focusing on those with a QRS duration of ≥130 ms. Patients were categorized into those receiving ICD-only or CRT-D. Key findings: Among patients with left bundle branch block (LBBB), those with CRT-D showed a significant 44% reduction in the risk of fast ventricular tachycardia (VT)/ventricular fibrillation (VF) compared to ICD-only patients. They also had a lower fast VT/VF burden and fewer appropriate shocks. In patients with non-left bundle branch block (NLBBB), CRT-D did not reduce the risk of fast VT/VF and was associated with a significant increase in the burden of fast VT/VF events compared to ICD-only patients. The study concludes that CRT-D effectively reduces life-threatening ventricular arrhythmias in LBBB patients but may increase the risk in NLBBB patients. https://www.hrsonline.org/education/TheLead https://www.jacc.org/doi/10.1016/j.jacep.2023.09.018?s=03 Host Disclosure(s): D.

Contributor: Travis Barlock MD Educational Pearls: Wide-complex tachycardia is defined as a heart rate > 100 BPM with a QRS width > 120 milliseconds Wide-complex tachycardia of supraventricular origin is known as SVT with aberrancy Aberrancy is due to bundle branch blocks Mostly benign Treated with adenosine or diltiazem Wide-complex tachycardia of ventricular origin is also known as VTach Originates from ventricular myocytes, which are poor inherent pacemakers Dangerous rhythm that can lead to death Treated with amiodarone or lidocaine 80% of wide-complex tachycardias are VTach 90% likelihood for patients with a history of coronary artery disease In assessing a wide-complex tachycardia, it is best to treat it as a presumed ventricular tachycardia Treating SVT with amiodarone or lidocaine does no harm However, treating VTach with adenosine or diltiazem may worsen the condition References 1.

To pass the written ACLS exam and mega code, students need to be able to identify basic ECG dysrhythmias, including the two types of second-degree heart block. One method of ECG rhythm identification is to ask a series of questions such as:What's the rate (150); Is the rhythm regular or irregular;What's the shape, width, and frequency of P waves and QRS complexes; andWhat's the P-R interval and is it constant?ECG characteristics of a second-degree Mobitz type I (Wenckebach).Identification of unstable bradycardia and its treatment with Atropine.ECG characteristics of a second-degree Mobitz type II.Possible effect of using Atropine on patients with a second-degree type II AV block.

BRASH es un acrónimo relativamente nuevo que describe un síndrome de bradicardias con hipotensión severa en el contexto de fallo renal e hiperkalemia. Usted está atendiendo a un masculino de 62 años de edad con debilidad general y desorientación progresivamente peor desde hace varias horas. Mantiene su propia vía aérea y respira espontáneamente, pero no tiene pulsos periféricos palpables. Los signos vitales son 28, 20, 86%, 82/38. Usted coloca al paciente en el monitor cardiaco y observa un bloqueo AV de 3er grado sin ondas P y con un complejo de escape ventricular. De inmediato le coloca oxígeno al paciente mediante mascarilla de no-reinhalación, obtiene dos accesos vasculares, administra 1 mg de atropina y se prepara para realizar intervenciones de segunda línea para aumentar la frecuencia cardiaca, entre ellas, la administración de una infusión de adrenalina y la colocación de un marcapasos externo. Los algoritmos están hechos para evitar desastres. No necesariamente representan el mejor cuidado posible. En este caso, el algoritmo de bradicardia nos dice qué acciones debemos hacer de inicio para mantener al paciente vivo. Sin embargo, no está funcionando. ¿Por qué? Debido a la hiperkalemia. Los medicamentos que causan bloqueo de la conducción a través del nodo atrioventricular (AV) pueden provocar episodios de hipotensión severa y refractaria en el contexto de fallo renal agudo. Bloqueo AV + fallo renal agudo El fallo renal puede ocurrir por cualquier causa no relacionada. El fallo renal pre-renal puede ocurrir, por ejemplo, por deshidratación severa o cualquier otra causa de pobre perfusión sistémica. El fallo renal produce hiperkalemia. La hiperkalemia y el bloqueo del nodo AV por los bloqueadores beta y/o por los bloqueadores de canales de calcio produce la hipotensión. BRASH: un acrónimo a recordar cuando se trata bradicardias sintomáticas Bradicardia Fallo Renal Bloqueo AV Shock Hiperkalemia Cada una de estas condiciones presenta un problema por sí mismo. Cuando se combinan, tienen un efecto sinergístico. Es decir, tiene un efecto más potente que la suma de sus partes individuales. BRASH no es un diagnóstico por separado, sino una descripción de los signos y síntomas asociados al ciclo vicioso de bradicardia, shock, fallo renal e hiperkalemia. Ciclo vicioso de bradicadia, shock, fallo renal e hiperkalemia La bradicardia puede venir por los medicamentos y/o por la hiperkalemia. En el paciente que ya toma estos medicamentos de forma continua, es posible que un deterioro súbito en la función renal de paso a la hiperkalemia. La causa del deterioro súbito de la función renal puede ser por cualquier causa pre-renal, renal o pos-renal. Una causa común de fallo renal pre-renal es cualquier causa de shock que provoque un episodio sostenido de pobre perfusión renal. El resultado es un aumento en los niveles de potasio debido a la pobre eliminación renal. La hiperkalemia produce bloqueo AV y bradicardia, lo que puede agravar aún más la bradicardia y agravar aún más la pobre perfusión renal, lo que provoca a su vez una peor hiperkalemia. SAMPLE El historial clínico del paciente es fundamental para entender el problema. Signos y síntomas Alergias Medicamentos Padecimientos Última ingesta ("last meal") Evento que precedió la emergencia Pistas importantes del historial El historial puede dar a relucir el hecho de que el paciente esté tomando medicamentos que bloquean el nodo AV. Quizás un cambio reciente en la dosis, o la introducción de otro medicamento que tenga un efecto en los niveles de potasio puede ser el detonante reciente. El historial puede dar a relucir el hecho de que el paciente ya padezca de una condición renal previa. El historial puede dar a relucir algún evento reciente que haya provocado el deterioro agudo en la función renal. Trate la bradicardia, la hiperkalemia y la causa de la pobre perfusión El manejo de la bradicardia puede no ser suficiente para lograr estabilizar hemodinámicamente al paciente con BRASH. Es importante reconocer rápidamente y tratar de inmediato de la hiperkalemia. Aunque las ondas T picudas e hiperagudas son signos clásicos de la hiperkalemia, son signos demasiado tempranos. La evolución natural de la condición va a producir bloqueo AV y prolongamiento del complejo QRS. Es decir, es la propia bradicardia y bloqueo AV el mejor signo de que el paciente puede tener una hiperkalemia. Simultáneo al manejo de la bradicardia y de la hiperkalemia, es esencial tratar la causa que está provocando la pobre perfusión renal (por ejemplo, fallo pre-renal por pobre perfusión). Si esto no se corrige, el escenario va a volver a repetirse. Pequeños estímulos con grandes efectos Como mencionado anteriormente, el efecto de esta combinación es sinergístico. Es decir, el efecto combinado es más grande que la suma de sus efectos individuales. No tiene que haber ocurrido un cambio en la dosis que el paciente está tomando del medicamento que bloquea el nodo AV, ni tiene que ser una dosis especialmente alta. Puede ser la misma dosis que ha tomado por largo tiempo sin efectos adversos. Un episodio reciente de deshidratación no tiene que llevar a fallo renal pre-renal. Sin embargo, en presencia del efecto del medicamento que bloquea el nodo AV, tiene un efecto dramático en el riñón. La hiperkalemia no tiene que ser de inicio muy alta. Es decir, no hay una correlación entre niveles específicos de potasio en sangre y los efectos observados. Peor aún, los cambios en el EKG no necesariamente van a progresar de la misma manera que siempre se habla de la hiperkalemia (primero ondas T hiperagudas). Como mencioné anteriormente, la bradicardia quizás es el único indicio. Entonces, cada uno de los estímulos no tiene que ser muy significativo: una dosis normal del medicamento que siempre ha tomado, un episodio relativamente benigno de deshidratación (por ejemplo), un nivel de potasio levemente elevado... pero la combinación produce una bradicardia severa, con fallo renal, bloqueo AV, shock e hiperkalemia... mejor conocido como BRASH.
