Electrophysiological Mechanisms and Determinants of Vagal Maneuvers for Termination of Paroxysmal Supraventricular Tachycardia

Abstract

Both the vagal response and conduction properties of the reentrant circuit determine the tachycardia termination by vagal maneuvers. Improved understanding of the interaction of autonomic and electrophysiological mechanisms in maintaining or terminating PSVT may provide important insight into the pathophysiology of these two tachycardias.
