Regular tachycardia terminated by ventricular anti-tachycardia pacing in an ICD recipient. What is the mechanism?

Acta Cardiol. 2013 Aug;68(4):443-5. doi: 10.1080/ac.68.4.2988902.

Abstract

This is the case of a misdiagnosed atrioventricular nodal reentry tachycardia (AVNRT) with occasionally 2:1 atrioventricular block terminated by delivery of an inappropriate ventricular antitachycardia pacing scheme, in an ICD recipient. The detailed analysis of stored electrograms facilitated the revelation of the arrhythmic mechanism.
