Abstract

Paroxysmal supraventricular tachycardia (PSVT) is commonly caused by reentry within the atrioventricular (AV) node. This arrhythmia was abolished by operative dissection of the AV junction in a patient with disabling tachycardia that was not controlled by drugs. The operation was intended to create complete AV block, but AV conduction persisted after surgery. An electrophysiologic study 1 year after the operation revealed that the operation changed AV conduction in both the antegrade and retrograde directions, which may explain the absence of tachycardia. The patient has been free of arrhythmias for 18 months.

摘要

阵发性室上性心动过速（PSVT）通常由房室（AV）结内折返引起。一名患有顽固性心动过速且药物无法控制的患者，通过手术解剖房室交界区使这种心律失常得以消除。该手术旨在造成完全性房室传导阻滞，但术后房室传导仍然存在。术后1年的电生理研究显示，手术改变了房室传导的顺行和逆行方向，这可能解释了心动过速消失的原因。该患者已18个月未发生心律失常。
