FIGHT AFIB IN DEPTH
Stop Piecing Together AFib Advice Get Clear Answers Every Week
Fight AFib brings you clear, evidence-based articles from Dr. Yasser Rodriguez, a board-certified cardiac electrophysiologist. Each week, one article is free. Paid members receive two additional in-depth articles, giving them all three new articles each week.
A short appointment cannot always cover everything. Fight AFib closes that gap — one clear article at a time.
AFib tends to beget more AFib. Every month without answers is a month you could’ve been building a real plan.
AFib questions rarely end when the appointment does
A diagnosis may begin with an emergency room visit, a smartwatch alert, a routine examination, or a symptom you cannot explain. Then come the questions: How serious is this? Do I need a blood thinner? When should I consider ablation? Which symptoms should send me to the emergency room? What can I change myself?
A short appointment cannot always cover everything, and searching online often produces a mixture of outdated guidance, personal anecdotes, and advice with no context. Even a helpful video may leave you wanting the evidence, the nuance, and a written explanation you can revisit later.
Fight AFib was created to close that gap. It gives patients and families one trusted place to return to for clear explanations, practical context, and better questions to bring to their own healthcare team.
Written by the specialist who answers these questions every day
Dr. Yasser Rodriguez, MD, MBA
Cardiac Electrophysiologist — Atrial Fibrillation & Complex Heart Rhythm Disorders
I am Dr. Yasser Rodriguez, a board-certified cardiac electrophysiologist focused on atrial fibrillation and complex heart rhythm disorders. I completed advanced electrophysiology training at Brigham and Women’s Hospital, a major Harvard teaching hospital, and I have authored more than 30 peer-reviewed publications and book chapters.
More importantly for this publication, I spend my clinical life listening to the questions patients ask when a diagnosis, medication, procedure, or symptom does not make sense yet. Those questions shape what I write.
Each Fight AFib article starts with a real patient concern. I then explain what the evidence shows, where uncertainty remains, and what questions may be worth discussing with your own care team. The goal is not to replace your physician. It is to help you understand the conversation.
Start with the Article Behind Our Most-Watched Video
Our most-watched Fight AFib YouTube video reached hundreds of thousands of viewers because it addressed a frightening problem: stroke warning symptoms can appear briefly, disappear, and be easy to dismiss.
The accompanying article shows what the Substack adds. A video can introduce the warning. A written article gives you room to slow down, revisit the details, save the explanation, and share it with the people who need it.
Five Symptoms Your Brain Uses to Warn You Before a Stroke
A transient warning sign that resolves in minutes can still mean a major stroke is days away — here’s what your brain may be trying to tell you, and why the 48 hours after matter most.

Who Fight AFib is written for
- People who were recently diagnosed and are still trying to understand what AFib means
- People who have lived with AFib for years but want clearer information about modern treatment options
- Patients deciding what to ask about blood thinners, ablation, pulse field ablation, WATCHMAN, or other therapies
- People who discovered AFib through a smartwatch, a routine examination, an emergency room visit, or a stroke evaluation
- Family members and caregivers who want to understand what their loved one is facing
- Readers who value evidence-based education but do not want to work through medical jargon
Fight AFib is educational. It is not a substitute for individualized diagnosis or treatment, and it is not a channel for personal medical advice. Its purpose is to help you understand AFib well enough to have a more informed conversation with the clinicians who know your history.
Turn scattered information into better questions
The goal is not to make you your own electrophysiologist. It is to help you stop feeling like a bystander in your own care.
Over time, you should be able to recognize the questions that matter, understand the trade-offs behind common treatment decisions, and walk into appointments with a clearer sense of what you need to discuss.
You do not have to learn everything about AFib today. You need one reliable place where you can keep learning, one article at a time.
