Video Transcription

Video Summary

Andres Enriquez, Cardiac Electrophysiologist from Queen's University, discusses the use of an electrocardiogram (ECG) to predict the origin of ventricular arrhythmias. He explains that certain features on the ECG can help determine the site of origin, such as the axis in leads 2 and 3, bundle branch block pattern, QRS duration, and precordial transition. He also mentions the value of the frontal plane axis and precordial transition specifically for outflow tract PVCs. Enriquez concludes by mentioning key morphological features that can suggest a particular site of origin, providing examples like parahysian PVCs, PVCs from the left cusp or anterolateral mitral annulus.
