Three Heart Rhythm Specialists Looked at the Same ECG. They Didn't Agree

So which diagnosis is actually correct? In this video, Dr. Scott Lee shares the story of a patient named Tom, who received three different explanations for the same heart rhythm. The experience left him questioning which doctor to trust—and whether the treatment being recommended was even the right one. The truth is, not every fast heart rhythm is AFib. Different abnormal heart rhythms come from different areas of the heart, carry different risks, and require different treatments. That's why getting the diagnosis right is one of the most important steps before making any treatment decisions. In this video, you'll learn: • Why different doctors can interpret the same heart rhythm differently • The story of Tom and why he received conflicting diagnoses • The difference between AFib, atrial flutter, and supraventricular tachycardia (SVT) • Why a fast heart rate is not the same thing as an abnormal heart rhythm • How heart rhythm specialists interpret EKGs differently than other physicians • Why the correct diagnosis determines the correct treatment • Which abnormal heart rhythms increase stroke risk—and which don't • Which heart rhythms can become life-threatening • Why AFib progresses differently than other arrhythmias • The three questions Dr. Scott Lee uses to evaluate every abnormal heart rhythm • Why an accurate diagnosis leads to better treatment decisions and greater confidence If you feel like you understand the pieces but aren’t sure how to put them together for your situation, I created a structured program that walks through this step by step. 🧭 AFib Clarity Program: 👉 https://heart.drscottlee.com/clarity 👨‍⚕️ About Dr. Scott Lee Dr. Scott Lee is a board-certified cardiac electrophysiologist with over 20 years of experience specializing in the treatment of complex and advanced atrial fibrillation.
