title: One tachycardia with two entrainment responses: what is the mechanism?
abstract: The patient presented for electrophysiology study and ablation for a history of narrow complex tachycardia. Both typical and atypical atrioventricular nodal reentrant tachycardia (AVNRT) were induced. For the atypical AVNRT, two different entrainment responses were recorded owing to different timing in delivering the ventricular pacing train.
