Diagnosis of SVT in the EP lab

(see below for quick links to jump to topics!) Here are the fundamentals of using intracardiac egms to diagnose the mechanism of SVT. I discuss findings during sinus rhythm, baseline pacing, in SVT, and with pacing maneuvers. Join the club of EP! 1. Introduction - 0:00 2. Baseline sinus and programmed stim pacing - 7:47 3. Is there a forward conducting accessory pathway? - 14:48 4. Is there a backward conducting accessory pathway? - 26:53 5. Para-Hisian pacing - 53:59 6. Is there dual AV node physiology? - 1:09:02 7.
