摘　　要：阵发性室上速(PSVT)中最常见的发作模式即为房室结折返性心动过速(AVNRT),其解剖学基础为房室结双径路,发作机制至今未明,但随着AVNRT患者的房室结慢径消融术的广泛开展,手术成功率高和复发率低使其成为治疗AVNRT的首选方法。近些年来研究发现AVNRT患者房室结慢径区域的迷走神经及其丰富,房室结慢径消融术可以去除迷走神经,不仅能治愈AVNRT,而且还能对降低阵发性房颤的易感性有一定的效果。因此,研究AVNRT患者房室结慢径消融术后迷走神经功能的改变对研究AVNRT与房颤的机制及其治疗的临床意义极为重要。Atrioventricular tachycardia(AVNRT)is the most common type of PSVT basisfor dual atrioventricular nodal pathway,its mechanism has not yet see clear,but with AVNRT ablation of the atrioventricular node slow pathway in patients were extensively developed,and high success rate and low recurrence rate make it the preferred method to treat AVNRT.In recent years,it has been found that there is a rich vagus nerve in the region of the AVNRT,patients with AVNRT regular diameter slow atrioventricular node ablation can remove the vagus nerve,can not only cure AVNRT,but also to reduce the susceptibility of atrial fibrillation has certain effect.Therefore,it is of great clinical significance to study the mechanism and treatment of atrioventricular tachycardia and atrial fibrillation in patients with AVNRT.
