Atrial fibrillation, or AFib, is one of the most common heart rhythm disorders—and it's not just something to worry about "when you're older." In this episode, Dr. Arfaat Khan, a cardiac electrophysiologist, explains what AFib is, the symptoms you shouldn't ignore, who may be at risk, and why catching and treating it early can make a real difference. We also talk about catheter ablation, a minimally invasive treatment that can help restore a normal heart rhythm, and why more patients may benefit from knowing this option exists. For more information about what Dr. Khan discussed in this episode, go to GetSmartAboutAFib.com  Transcript: 06:14:16 --> 06:14:19 Dr. Arfaat Khan: Hi Marijo, thank you for having me on the show. 06:14:18 --> 06:14:23 Marijo Tinlin: Hey, thank you. Absolutely. Let me get started here. 06:14:27 --> 06:14:48 Marijo Tinlin: Hello, this is Marijo Tinlin from the Teaching Your Toddler show. Today we have a great episode. We are recording in September, which is the beginning of AFib Awareness Month, and we have a special guest, Dr. Arfaat Khan, is with us to talk to us about that. So, first of all, doctor, welcome to the show. Tell us a little bit. What is AFib? 06:14:48 --> 06:14:59 Dr. Arfaat Khan: So, thank you, Marijo, for having me on the show today. So, atrial fibrillation, also known as AFib, is a very common heart rhythm disorder in which the top chambers of the heart start to beat periodically. 06:14:59 --> 06:15:10 Dr. Arfaat Khan: It's a very common condition. Over 55 million people globally are affected by it, and if left untreated, it can lead to serious complications. 06:15:10 --> 06:15:14 Marijo Tinlin: Oh, wow. So how do you know that you have it? 06:15:14 --> 06:15:23 Dr. Arfaat Khan: So, patients can present with different types of symptoms. You can have anxiety, palpitations, feeling your heart skipping beats. 06:15:23 --> 06:15:31 Dr. Arfaat Khan: Uh, feeling tired, short of breath, basically having difficulty carrying on the normal routines that you're able to do without any problem. 06:15:31 --> 06:15:44 Dr. Arfaat Khan: You have to understand that AFib is a progressive condition. It starts out in the early stage and then can later progress down to the point where you can't get rid of it, so that's why it's very, very important to identify it and treat it early. 06:15:44 --> 06:15:58 Dr. Arfaat Khan: And it's also important that if you are diagnosed with atrial fibrillation, that you should be referred to a cardiac electrophysiologist, which is actually a specialized cardiologist who are specially trained to identify and manage the different aspects of atrial fibrillation. 06:16:00 --> 06:16:06 Marijo Tinlin: What? Can you explain what an electrophysiologist is? That's you. 06:16:05 --> 06:16:18 Dr. Arfaat Khan: Yeah, so I'm an electrophysiologist, so an electrophysiologist is basically a physician that's actually a cardiologist, but has advanced training in managing different heart rhythm disorders, and AFib is actually one of the most common heart rhythm disorders. 06:16:17 --> 06:16:26 Marijo Tinlin: Oh, wow. Okay, so how old do you tend to see your patients, or how early should a patient start to think about this? 06:16:26 --> 06:16:41 Dr. Arfaat Khan: So, recent studies show that the earlier you diagnose AFib and treat it, the better the outcomes, because AFib is a progressive condition. Um, so within, you know, a month to at least within a year of treatment of AFib actually leads to better patient outcomes. 06:16:42 --> 06:16:47 Marijo Tinlin: Are there any pre-existing conditions that you tend to see with patients? 06:16:47 --> 06:16:58 Dr. Arfaat Khan: So some patients can have, like, hypertension, diabetes, you know, history of heart failure, but generally, the older you get, these are the more common risk factors of development of AFib. 06:16:59 --> 06:17:04 Marijo Tinlin: And so, there are some new options for treatment that you're going to tell us about. 06:17:04 --> 06:17:19 Dr. Arfaat Khan: Yeah, although there are different, many treatment options available, catheter ablation is a very safe, minimally invasive procedure in which we go into the heart and help identify where the faulty electrical signals are, target them, and help restore normal rhythm. 06:17:19 --> 06:17:33 Dr. Arfaat Khan: It's an outpatient procedure. Um, as I said, it's minimally invasive. Most patients are able to go home that same day. They have little to no discomfort after the procedure, and typically they resume their normal activities within a few days after the procedure is done. 06:17:33 --> 06:17:48 Dr. Arfaat Khan: I personally use the Cardo 3D electroanatomical mapping system, and this mapping system helps me reconstruct the patient's heart's anatomy, and also helps me localize where the faulty electrical signals are, so that I can specifically tailor each therapy. 06:17:48 --> 06:17:54 Dr. Arfaat Khan: individual to the patient. And that actually leads to improved patient success and improved patient outcomes. 06:17:54 --> 06:18:05 Dr. Arfaat Khan: But it's important to understand that although 55 million people globally are affected by atrial fibrillation, only 5% of eligible patients are actually getting this catheter ablation procedure done. 06:18:05 --> 06:18:13 Marijo Tinlin: Is that just because they don't know or is it because doctors don't know to refer this or what's causing that? 06:18:12 --> 06:18:26 Dr. Arfaat Khan: I think it's a common, you know, it's a multitude of different things, right? With September being AFib Awareness Month, our goal is to help increase awareness about what AFib is, and what therapies are actually available to treat atrial fibrillation, such as catheter ablation. 06:18:26 --> 06:18:32 Marijo Tinlin: Excellent. So is it usually referred from a PCP then? Sorry, a primary care physician? 06:18:32 --> 06:18:49 Dr. Arfaat Khan: Yeah, primary care physician, ER physicians, cardiologists, anyone can actually refer to a cardiac electrophysiologist. But as a patient, there are multiple different resources available too. So if you think you have AFib, Johnson & Johnson actually has a website called GetSmartAboutAFib.com. 06:18:49 --> 06:18:57 Dr. Arfaat Khan: Which actually has a lot of educational videos, testimonials, and even a questionnaire to see if you qualify for a catheter ablation procedure. 06:18:57 --> 06:19:12 Marijo Tinlin: Oh, excellent. Well, thank you. Of course, I was going to ask you for more information, so we'll make sure that that link is available for the listeners. Thank you so much. This is a fascinating topic, and I'm glad that you brought it. And thank you so much for joining us today. 06:19:11 --> 06:19:14 Dr. Arfaat Khan: Thank you very much for having me. Appreciate it. 06:19:13 --> 06:19:15 Marijo Tinlin: Absolutely.   Dr. Arfaat Khan's biography:  Dr. Arfaat Khan is a board-certified cardiac electrophysiologist specializing in the diagnosis and treatment of heart rhythm disorders, including atrial fibrillation, supraventricular tachycardia, ventricular arrhythmias, cardiac device implantation, and complex catheter ablation procedures. He is also an Assistant Professor of Medicine at Wayne State University and Michigan State University, where he is actively involved in teaching the next generation of physicians.

Could retirement actually become the beginning of your most meaningful work? In this personal solo episode, Dr. Gillian Lockitch shares how spinal surgery, ballroom dancing, entrepreneurship and podcasting transformed her understanding of healthy longevity. You'll discover why curiosity, consistency and a renewed sense of purpose can help you remain mentally sharp, physically engaged and excited about the future at any age.  For most of her professional life, Dr. Gillian Lockitch was a physician, medical biochemist, researcher, university professor and department head. She expected retirement to bring more travel, reading, dancing and time with her family—not a new career as an entrepreneur, author, podcast host and healthy longevity advocate. Her journey changed when severe spinal stenosis led to emergency surgery and a lengthy recovery. Faced with the challenge of regaining her strength, mobility and independence, Gillian began exploring healthy aging not simply as a scientist, but as someone personally determined to age differently. That shift in perspective became the foundation of Growing Older Living Younger. In this episode, Gillian describes how curiosity led her from exploring a Wellness Trade Show into entrepreneurship at 70. She explains how her scientific training shaped the way she evaluated wellness products and opportunities, why she remained committed to evidence, and how she discovered that people were looking for trusted guidance rather than another sales presentation. She also shares the lessons she learned from ballroom dancing, building a business, adapting during the COVID-19 pandemic, writing a book and launching a podcast on her 76th birthday. Each new undertaking required her to become a beginner again, develop unfamiliar skills and learn that consistency is more important than occasional intensity.  Finally Gillian reflects on the setbacks and opportunities that have shaped her purpose. Her message is simple but powerful: your purpose has no expiry date, retirement does not have to mean withdrawal from action, and reinvention is possible for anyone who remains curious. Although we inherit our genetic blueprint, everyday lifestyle choices can affect how our genes are expressed—and ultimately  help us live gracefully as we grow older.

This week we speak with Dr. Ted O'Leary, Co-Director of Adult Congenital Heart Disease Electrophysiology at Boston Children's Hospital about a recent publication he authored on the use of pulsed field ablation (PFA) for the transcatheter ablation management of complex atrial arrhythmias in ACHD patients. How does PFA work and what are some of the potential advantages and disadvantages of this novel ablation energy technology? What are the advantages of a variable loop catheter in this setting? Is PFA going to supplant radiofrequency current for standard "SVT" ablations one day? These are amongst the questions reviewed with Dr. O'Leary this week. DOI: 10.1161/CIRCEP.125.014619

Commentary by Dr. Timothy Ka-chun UN.

In this episode of the JACC: Clinical Electrophysiology podcast, Executive Editor Emile Daoud discusses the primary analysis of the HEAL‑LAA study. The paper by Oluseun Alli, et al, evaluates real‑world outcomes with a next‑generation, fluoropolymer‑coated left atrial appendage occlusion device. In 500 patients across 32 U.S. centers, the study demonstrated excellent early device sealing, no significant peri‑device leaks, and favorable safety outcomes through 12 months, offering timely insights into contemporary LAAC practice and post‑implant antithrombotic management.

In this episode, Jeremy Moore, MD, MS, Associate Editor of JACC: Clinical Electrophysiology, reviews a study showing that adults with Ebstein anomaly face a high lifetime risk of atrial arrhythmias, with more than half developing one by age 60. The most common arrhythmias were intra-atrial re-entrant and focal atrial tachycardias, which were more frequent than atrial fibrillation. Older age, prior cardiac surgery, significant tricuspid valve leakage, and severe right ventricular dysfunction were key risk factors, underscoring the need for lifelong specialized follow-up.

No Click Valvar de hoje temos grandes insights sobre a abordagem de fibrilação atrial em casos de regurgitação tricúspide.

Durante anos, a prevenção de AVC na fibrilação atrial seguiu uma lógica relativamente simples: identificar o risco tromboembólico e prescrever anticoagulação.Mas a prática clínica mostrou que a equação é mais complexa.Sangramentos maiores, hemorragias intracranianas, baixa adesão, fragilidade, quedas recorrentes e limitações socioeconômicas frequentemente colocam médicos e pacientes diante de decisões difíceis.No Ep. 228 do DozeCast, os hosts Diandro Motta e Victor Bemfica, recebem a cardiologista Dra. Brunna Pileggi e a neurologista Dra. Gisele Sampaio para analisar em profundidade o Champion-AF, estudo que avalia o fechamento percutâneo do apêndice atrial esquerdo (LAAC) com dispositivo Watchman como alternativa à anticoagulação oral direta em pacientes com fibrilação atrial.A grande provocação do estudo é simples: devemos continuar reservando o fechamento do apêndice atrial apenas para situações extremas ou chegou o momento de antecipar essa decisão?O que você vai aprender:

Commentary by Dr. Jian'an Wang.

Left atrial appendage closure—promise meets proof, and proof meets pause.   In The New England Journal of Medicine, two pivotal trials draw a nuanced arc: CHAMPION-AF shows noninferior stroke prevention with less bleeding vs direct oral anticoagulants, while CLOSURE-AF tempers enthusiasm—failing noninferiority in older, high-risk patients with meaningful procedural risk.   The message is elegant and sobering: innovation must bow to evidence, and patient selection remains paramount.   In atrial fibrillation, the art lies not in closing the appendage—but in opening judgment.

Join Digital Education Committee member and podcast host Melissa E. Middeldorp, MPH, PhD, along with this week's guest contributors, Joshua Silverstein MD, FHRS from Allegheny Health Network and Jonathan Ariyaratnam, BChir, MA, MB, CCDS, CEPS-A from the University of Adelaidefor this week's episode. This study by Vad and colleagues examined markers of atrial cardiomyopathy (AtCM) in 26,467 UK Biobank participants without prior atrial fibrillation (AF), heart failure (HF), or stroke, integrating cardiac MRI, ECG, clinical risk factors, and genetic data. AtCM was defined using four markers: left atrial dilation, reduced left atrial emptying fraction (120 ms), and abnormal P-wave terminal force and 15.7% of individuals had at least one marker, while 2.3% had two or more. Over a median follow-up of nearly five years, the presence of AtCM markers showed a dose–response relationship with incident AF, with a HR: 4.59 in those with ≥2 markers and was also strongly associated with HF and ischemic stroke. Adding AtCM markers to clinical and genetic risk models improved AF risk prediction, supporting the concept that atrial cardiomyopathy may represent a common substrate linking AF, HF, and stroke and may help refine future risk stratification strategies. Article for Discussion Learning Objectives Understand how imaging- and ECG-based markers of atrial cardiomyopathy are defined and how they relate to the risk of incident AF, heart failure, and stroke. Evaluate how integrating atrial cardiomyopathy markers with clinical and genetic risk scores may improve risk stratification for AF and related cardiovascular outcomes.

Atrial fibrillation is the most common sustained cardiac arrhythmia, affecting ~37.6 million people globally, with prevalence expected to double in the coming decades.    A recent Lancet Seminar (2026) highlights several key principles shaping modern AF care:   • Stroke prevention with oral anticoagulation remains the cornerstone • Early rhythm control strategies improve cardiovascular outcomes • Catheter ablation is increasingly used as first-line therapy • Lifestyle modification—weight loss, exercise, alcohol reduction—reduces AF burden • Integrated care models such as the ABC pathway and AF-CARE improve outcomes   The future of AF management is holistic, preventive, and patient-centred.   #Cardiology #AtrialFibrillation #StrokePrevention #Electrophysiology #PrecisionMedicine

This week we review a recent work on fetal atrial septal interventions in the patient with hypoplastic left ventricle or double outlet right ventricle with mitral valve atresia/dysplasia and a restrictive or intact atrial septum. How often was this procedure technically feasible and successful? What are the criteria to be considered for such an intervention? Why does use of a laser improve the crossing of the atrial septum in this procedure? Should prenatal intervention be used instead of postnatal intervention in this setting? Associate Professor of Pediatrics at Baylor College of Medicine, Dr. Betul Yilmaz shares her insights into this fascinating topic.https://doi.org/10.1161/CIRCINTERVENTIONS.125.015209

Cardiomiopatia atrial – Critérios Diagnósticos by Cardiopapers

In this episode, the CardioNerds (Dr. Naima Maqsood, Dr. Akiva Rosenzveig, and Dr. Colin Blumenthal) are joined by renowned educator in electrophysiology, Dr. Joshua Cooper, to discuss everything atrial flutter; from anatomy and pathophysiology to diagnosis and management. Dr. Cooper's expert teaching comes through as Dr. Cooper vividly describes atrial anatomy to provide the foundational understanding to be able to understand why management of atrial flutter is unique from atrial fibrillation despite their every intertwined relationship. A foundational episode for learners to understand atrial flutter as well as numerous concepts in electrophysiology. Audio editing for this episode was performed by CardioNerds intern Dr. Bhavya Shah.  CardioNerds Atrial Fibrillation PageCardioNerds Episode PageCardioNerds AcademyCardionerds Healy Honor Roll CardioNerds Journal ClubSubscribe to The Heartbeat Newsletter!Check out CardioNerds SWAG!Become a CardioNerds Patron! Pearls "The biggest mistake is failure to diagnose”. Atrial flutter, especially with 2:1 conduction, is commonly missed in both inpatient and outpatient settings so look carefully at that 12-lead EKG so you can mitigate the stroke and tachycardia induced cardiomyopathy risk  Decremental conduction of the AV node makes it more challenging to rate control atrial flutter than atrial fibrillation  Catheter Ablation is the first line treatment for atrial flutter and is highly successful, but cardioversion can be utilized as well prior to pursuing ablation in some cases.  Class I AADs like propafenone and flecainide may stability the atrial flutter circuit by slowing conduction and thus may worsen the arrhythmia. Therefore, the preferred anti-arrhythmic medication in atrial flutter are class III agents.  Atrial flutter can be triggered by firing from the left side of the heart, so in patients with both atrial fibrillation and flutter, ablating atrial fibrillation makes atrial flutter less likely to recur.  BONUS PEARL: Dr. Cooper's youtube video on atrial flutter is a MUST SEE!  Notes Notes: Notes drafted by Dr. Akiva Rosenzveig  What are the distinguishing features of atrial fibrillation and flutter?  Atrial flutter is an organized rhythm characterized by a wavefront that continuously travels around the same circuit leading to reproducible P-waves on surface EKG as well as a very mathematical and predictable relationship between atrial and ventricular activity  Atrial fibrillation is an ever changing, chaotic rhythm that consists of small local circuits that interplay off each other. Consequently, no two beats are the same and the relationship between the atrial activity and ventricular activity is unpredictable leading to an irregularly irregular rhythm  What are common atrial flutter circuits?  Cavo-tricuspid isthmus (CTI)-dependent atrial flutter is the most common type of flutter. It is characterized by a circuit that circumnavigates the tricuspid valve.  Typical atrial flutter is characterized by the circuit running in a counterclockwise pattern up the septum, from medial to lateral across the right atrial roof, down the lateral wall, and back towards the septum across the floor of the right atrium between the IVC and the inferior margin of the tricuspid valve i.e. the cavo-tricuspid isthmus. Surface EKG will show a gradual downslope in leads II, III, and AvF and a rapid rise at end of each flutter wave.   Atypical CTI-dependent flutter follows the same route but in the opposite direction (clockwise). Therefore, we will see positive flutter waves in the inferior leads   Mitral annular flutter is more commonly seen in atrial fibrillation patients who've been treated with ablation leading to scarring in the left atrium.  Roof-dependent flutter is characterized by a circuit that travels around left atrium circumnavigating a lesion (often from prior ablation), traveling through the left atrial roof, down the posterior wall, and around the pulmonary veins  Surgical/scar/incisional flutter is seen in people with a history of prior cardiac surgery and have iatrogenic scars in right atrium due to cannulation sites or incisions  How does atrial flutter pharmacologic management differ from other atrial arrhythmias?  The atrioventricular (AV) node is unique in that the faster it is stimulated, the longer the refractory period and the slower it conducts. This characteristic is called decremental conduction. In atrial fibrillation, the atrial rate is so fast that the AV node becomes overwhelmed and only lets some of those signals through to the ventricles creating an irregular tachycardia but at lower rates. In atrial flutter, the atrial rate is slower, therefore the AV node has more capability to conduct allowing for higher ventricular rates. Therefore, to achieve rate control one will need a higher dose of AV blocking medications. Atrial tachycardia may require even higher doses due to the increased ability of the AV node to conduct, as the atrial rates are slower than in atrial flutter.  Sodium channel blockers (Class I) such as flecainide and propafenone slow wavefront propagation, making it easier for the AV node to handle the atrial rates. This will end up leading to increased ventricular rates which can be dangerously fast. That is why AV nodal blockers should be used in conjunction with flecainide and propafenone.  What is the role of cardioversion in atrial flutter management?  Due to high success rate with atrial flutter ablation, ablation is the first line treatment. However, sometimes cardioversion may be utilized in patients depending on how symptomatic they are and how long it will take to get an ablation. Cardioversion may also be utilized preferentially when the atrial flutter was triggered by infection or cardiac surgery to see if it will come back.   If cardioversion is pursued, the patient will need to be anticoagulated due to the stroke risk after the procedure due to post-conversion stunning.  How effective is atrial flutter ablation?  The landmark Natale et al study in 2000 demonstrated 80% success rate after radiofrequency ablation as compared to 36% in patients on anti-arrhythmic therapy. The LADIP study in 2006 further corroborated these findings. Contemporary data shows above 90% success rate of atrial flutter ablation.  In patients who have had both atrial fibrillation and atrial flutter, most electrophysiologists would ablate both. However, in patients with atrial fibrillation, the atrial flutter usually is initiated by trigger spots firing in the left atrium. Once the atrial fibrillation is ablated, the flutter will become less likely. Therefore, there are those who say there's no need to ablate the flutter circuit as well. Alternatively, if a patient has severe comorbidities and/or is high risk for ablation, one may consider performing the atrial flutter ablation only since atrial flutter is harder to manage medically compared with atrial fibrillation.   How do you manage atrial flutter in the acute inpatient setting?  In the inpatient setting, electrical cardioversion is often limited by blood pressure and the hypotensive effects of the sedatives required. If one is awake and too hypotensive, chemical cardioversion can be pursued. The most effective anti-arrhythmic for this is ibutilide. Amiodarone is not effective for acute cardioversion. Since ibutilide prolongs refractoriness in atrial and ventricular tissue, there's a risk of long QT induced torsades de pointes. Pretreating with magneisum reduces the risk to 1-2%.  References Jolly WA, Ritchie WT. Auricular flutter and fibrillation. 1911.

Cardiomiopatia Atrial - Quando a IC começa pelos átrios by Cardiopapers

Dr. Naima Maqsood, Dr. Kelly Arps, and Dr. Jake Roberts discuss the acute management of atrial fibrillation with guest expert Dr. Jonathan Chrispin. Episode audio was edited by CardioNerds Intern Dr. Bhavya Shah. This episode reviews acute management strategies for atrial fibrillation. Atrial fibrillation is the most common chronic arrhythmia worldwide and is associated with increasingly prevalent comorbidities, including advanced age, obesity, and hypertension. Atrial fibrillation is a frequent indication for hospitalization and a complicating factor during hospital stays for other conditions. Here, we discuss considerations for the acute management of atrial fibrillation, including indications for rate versus rhythm control strategies, treatment targets for these approaches, considerations including pharmacologic versus electrical cardioversion, and management in the post-operative setting. CardioNerds Atrial Fibrillation PageCardioNerds Episode PageCardioNerds AcademyCardionerds Healy Honor Roll CardioNerds Journal ClubSubscribe to The Heartbeat Newsletter!Check out CardioNerds SWAG!Become a CardioNerds Patron! Pearls A key component to the management of acute atrial fibrillation involves addressing the underlying cause of the acute presentation. For example, if a patient presents with rapid atrial fibrillation and signs of infection, treatment of the underlying infection will help improve the elevated heart rate. Selecting a rate control versus rhythm control strategy in the acute setting involves considerations of comorbid conditions such as heart failure and competing risk factors such as critical illness that may favor one strategy over another. Recent data strongly supports the use of rhythm control in heart failure patients. Patients should be initiated on anticoagulation prior to pursuing a rhythm control strategy. There are several strategies for rate control medications with therapies including beta-blockers, non-dihydropyridine calcium channel blockers, and digoxin. The selection of which agent to use depends on additional comorbidities and the overall clinical assessment. For example, a patient with severely decompensated low-output heart failure may not tolerate a beta-blocker or calcium channel blocker in the acute phase due to hypotension risks but may benefit from the use of digoxin to provide rate control and some inotropic support. Thromboembolic prevention remains a cornerstone of atrial fibrillation management, and considerations must always be made in terms of the duration of atrial fibrillation, thromboembolic risk, and risks of anticoagulation. While postoperative atrial fibrillation is more common after cardiac surgeries, there is no major difference in management between patients who undergo cardiac versus non-cardiac procedures. Considerations involve whether the patient has a prior history of atrial fibrillation, surgery-specific bleeding risks related to anticoagulation, and monitoring in the post-operative period to assess for recurrence. Notes 1. Our first patient is a 65-year-old man with obesity, hypertension, obstructive sleep apnea, and pre-diabetes presenting for evaluation of worsening shortness of breath and palpitations. The patient has no known history of heart disease. Telemetry shows atrial fibrillation with ventricular rates elevated to 130-140 bpm. What would be the initial approach to addressing the acute management of atrial fibrillation in this patient? What are some of the primary considerations in the initial history and chart review? An important first step involves taking a careful history to understand the timing of symptom onset and potential underlying causes contributing to a patient's acute presentation with rapid atrial fibrillation. Understanding the episode trigger determines management by targeting reversible causes of the acute presentation and elucidating whether the episode is triggered by a cardiac or non-c...

Is your smartwatch just a fun gadget, or a serious medical device?  In this episode, Jonathan Wolf is joined by Dr. Malcolm Findlay, a leading consultant cardiologist, to explore the powerful health data available on your wrist. They decode the most misunderstood metric, Heart Rate Variability (HRV), and reveal how your wearable can provide clinical-grade insights into your heart's health. Dr. Findlay explains the counter-intuitive science behind HRV — why more ‘wobble' in your heartbeat is a sign of good health — and breaks down the two opposing nervous systems that control it. He shares the latest on how these devices can accurately detect serious conditions like atrial fibrillation and why he, as a cardiologist, trusts the ECG function on a consumer smartwatch to make diagnoses. For listeners who track their own data, this episode is a practical guide to what your numbers actually mean. Dr. Findlay explains how to interpret your personal HRV trends, what constitutes a significant change, and when you should use the ECG feature. He also debunks common myths about heart rate zones, revealing the level of exercise intensity that truly benefits your long-term health. The episode concludes with an empowering look at how this technology is shifting control into our own hands. Can a simple alert from your watch really help prevent a catastrophic event like a stroke? Discover which metrics matter most and how to use them to guide your wellness journey.

This week we replay an episode from 2 years ago on postoperative ectopic atrial tachycardia (EAT) following congenital heart surgery in children. Are there risk factors for this arrhythmia and are any modifiable? What is the 'go to' therapy used by the electrophysiologists at Children's LA for the acute and chronic treatment of this arrhythmia in the postoperative period? Is the presence of EAT in a postoperative congenital heart patient a marker for a worse outcome? These are amongst the questions posed to Children's of Los Angeles pediatric electrophysiologist, Dr. Jonathan Uniat. ·         DOI: 10.1007/s00246-022-03068-8

Think you might have AFib? Talk to your cardiologist or an electrophysiologist about testing and treatment. Host:Willard ShepardAward-Winning JournalistGuest:Bryan Wilner, M.D.Cardiac ElectrophysiologistBaptist Health Miami Cardiac & Vascular Institute

Dr. Kelly Arps, Dr. Naima Maqsood, and Dr. Sahi Allam discuss modifiable risk factors and lifestyle management of atrial fibrillation with Dr. Prash Sanders. Atrial fibrillation is becoming more prevalent across the world as people are living longer with cardiovascular disease. While much of our current focus lies on the pharmacological and procedural management of atrial fibrillation, several studies have shown that targeted reduction of risk factors, such as obesity, sleep apnea, hypertension, and alcohol use, can also significantly reduce atrial fibrillation burden and symptoms. Today, we discuss the data behind lifestyle management and why it is considered the “4th pillar” of atrial fibrillation treatment. We also explore ways to incorporate prevention strategies into our general cardiology and electrophysiology clinics to better serve the growing atrial fibrillation population. Audio editing for this episode was performed by CardioNerds Intern, Julia Marques Fernandes.  CardioNerds Atrial Fibrillation PageCardioNerds Episode PageCardioNerds AcademyCardionerds Healy Honor Roll CardioNerds Journal ClubSubscribe to The Heartbeat Newsletter!Check out CardioNerds SWAG!Become a CardioNerds Patron! Pearls More people have atrial fibrillation because it is being detected earlier using wearable technology, and patients are living longer with subclinical or clinical cardiovascular disease  There are 3 components of atrial fibrillation: an electrical “trigger” + a susceptible substrate (due to age, sex, genetics) + “perpetuators” that cause the trigger to continue stimulating the substrate (lifestyle risk factors such as obesity, smoking, diabetes, etc.)  Obesity is the highest attributable risk factor for atrial fibrillation. Treating obesity often helps to treat other risk factors, such as hypertension and sleep apnea.  Counseling is patient-dependent. Most patients are unable to make major behavioral changes cold-turkey and will need to make small, incremental changes.  Dr. Sanders' tip: He tells his own patients that “atrial fibrillation is the body's response to stress.” The key to treating atrial fibrillation is to control your underlying stressors - procedures and medications are simply band-aids that do not fix the root of the problem.  Notes Notes drafted by Dr. Allam. 1. How common is atrial fibrillation?  Atrial fibrillation is the most common sustained arrhythmia. Currently, an estimated 50-60 million individuals worldwide are estimated to have atrial fibrillation, or roughly 1 in 4 individuals over the age of 45.1  The rising global prevalence of atrial fibrillation can be attributed to the aging of the population, increased rates of obesity, and greater accumulation of cardiovascular risk factors and survival with clinical cardiovascular disease.2 Atrial fibrillation is also being detected earlier through digital and wearable devices.2  Annually, we spend approximately $5,312 per adult on the management of atrial fibrillation in the United States.3  2. What is the underlying pathophysiology of atrial fibrillation? How do risk factors like sleep apnea or obesity “trigger” atrial fibrillation?  For atrial fibrillation to occur, there is an electrical “trigger”, a susceptible substrate (due to age, sex, genetics), and “perpetuators” that allow the trigger to continue stimulating the substrate.2  90% of electrical “triggers” come from the pulmonary veins  “Perpetuators” influence how the autonomic nervous system interacts with the triggers and substrate to perpetuate atrial fibrillation. Sleep apnea, obesity, and other risk factors are the “perpetuators”  Over time, as atrial fibrillation recurs, the substrate remodels to result in persistent atrial fibrillation.  3. What are some of the risk factors for atrial fibrillation and what are the possible benefits of controlling them?

Story at-a-glance Atrial fibrillation (AFib) is typically linked to cardiovascular risk factors like hypertension and aging, but evidence suggests chronic oral infections also play a direct role in its development New research links Porphyromonas gingivalis, the key bacterium in gum disease, to heart scarring and arrhythmias. Findings show it travels to the heart and interferes with electrical signaling In animal models, P. gingivalis exposure increased AFib risk, while human heart tissue confirmed higher bacterial load and damage in patients with severe gum disease A 14-year study of 1.25 million people found chronic gum disease increased AFib risk by 4%, while recovery lowered risk to nearly the same level as gum-healthy individuals To improve your gum health, make sure to brush and floss daily, try oil pulling, eat a whole-food diet, manage your stress levels, and get regular cleanings from a biological dentist trained in systemic oral care
