摘　　要：房室结折返性心动过速(atrioventricular nodal reentry tachycardia,AVNRT)是临床上常见的阵发性室上性心动过速的类型之一,其解剖基础为房室结双径路(dual atrioventricular nodal physiology,DAVNP)。近年来研究发现DAVNP的慢径路区域分布有丰富的迷走神经,影响DAVNP的临床表现及电生理性质。深入了解迷走神经与DAVNP的关系对临床诊断和治疗具有重要的意义。Atrioventricular nodal reentrant tachycardia is a kind of clinically paroxysmal supraventricular taehycardia, anatom- ically based on dual atrioventricular nodal physiology （DAVNP）. Studies in the recent years find that there are plenty of vagi in the slow pathway area of DAVNP, affecting the clinical and electrophysiological characteristics of DAVNP. An insight into the relationship of DAVNP with vagi is significant for the diagnosis and treatment of the problem.
