Abstract

This 52‐year‐old male presented with syncope and demonstrated two distinct PR intervals on the electrocar‐diogram. Electrophysiologic studies showed dual A V nodal path ways. Right‐sided carotid sinus massage induced prolonged periods of sinus arrest with no change in AH interval. Left‐sided carotid sinus massage produced long AH intervals (slow pathway conduction) with some slowing of sinus rate. Whenever sinus rhythm with slow pathway conduction was observed (long AH) a 20‐30 mmHg drop systolic pressure was seen. Following implantation of an AV sequential pacemaker, the patient has been asymptomatic.
