Abstract

Introduction: Narrow complex tachycardias with a 1:1 atrioventricular (AV) relationship have characteristic features on surface electrocardiogram (ECG) and at the time of electrophysiology (EP) study. Differential diagnostic pacing maneuvers at the time of EP study have been well established; on most occasions the diagnosis can be made rapidly if the tachycardia response meets a criterion for the suspected mechanism. On occasion the response to pacing maneuvers can be atypical. Careful analysis of all diagnostic pacing maneuvers during tachycardia can lead to the diagnosis of a rare mechanism for tachycardia.
