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.

摘要

描述了一名PR间期短（0.10秒）、QRS波群窄且有心悸症状的患者。电生理研究显示存在房室（AV）结传导加速。随后，发现了嗜铬细胞瘤。手术切除肿瘤后PR间期恢复正常。这些发现表明，短PR间期和房室结传导加速是由于过量儿茶酚胺对房室传导系统的影响所致。
