Differentiation of narrow complex tachycardia
Many different criteria and pacing maneuvers exist to determine the etiology of a narrow QRS complex tachycardia (NCT). This report describes a case of NCT wherein the initial conflicting findings at the time of the EP study were then clarified by the development of left bundle branch block and prolongation of ventriculoatrial conduction time confirming the diagnosis of a left sided accessory pathway. The accessory pathway was then successfully ablated.
