Abstract

A patient with a short (0.10 second) PR interval, narrow QRS complex and palpitation is described. Electrophysiologic studies demonstrated the presence of accelerated atrioventricular (AV) nodal conduction. Subsequently, a pheochromocytoma was found. Surgical removal of the tumor resulted in normalization of the PR interval. These findings suggest that the short PR interval and the accelerated AV nodal conduction were due to the effect of excess catecholamines on the AV conduction system.
