Entrainment Basics and the Post-Pacing Interval

Education – Clinical: This Foundational EP educational video will review the basics of entrainment pacing during reentrant arrhythmias and the significance of the post-pacing interval. Attention will be paid to the specific circumstances that allow the myocardial reentry to occur, and a review of what happens when one performs pacing maneuvers and records electrograms during tachycardia. By starting and stopping pacing at different sites and analyzing what happens right after after pacing is stopped, the size and location of a reentry circuit can be determined. Additional videos created by Joshua M. Cooper, MD, FACC, FHRS include:

• Introduction to Intracardiac Electrograms
• Diagnosis of SVT in the EP Lab
• Atrial Flutter: Diagnosis and Ablation
• Activation Mapping: How it Works and How it Can Go Wrong
• Pace Mapping: Principles and Pitfalls
• TAVR and Pacemaker: Why Do Some People Get Both?
• Entrainment of Scar-Based Reentrant Ventricular Tachycardia
