New Video: ECG Interpretation of Atrial Fibrillation

Published October 1, 2026

We found a new Atrial Fibrillation video to share with readers of A-Fib.com. (Patti is always on the lookout for Instructional A-Fib Videos and Animations for the reader who learns visually through motion graphics, audio, and personal interviews.)

Intermediate Level: This video is for the reader already familiar with the ECG signal and wants a more in-depth understanding of the Atrial Fibrillation ECG signal.

Background Reading: You may want to review our page, Understanding the EKG Signal that gives the reader a basic understanding of the output of an ECG recorder. Specifically, the ECG signal strip graphic including the P wave, QRS Complex, the ST segment and the T wave.
