摘　　要：射频消融改良慢径是治疗房室结折返性心动过速（AVNRT）的一种安全有效的方法,文献报道其消融的成功率98.8%,复发率2.3%,并发症仅为0.8%,并且适用于老年人,其消融成功率及并发症与其他各年龄组一致[1-3]。但老年人传导系统功能减退[4],其房室结电生理特点与非老年人群有何异同以及消融放电反应、消融终点的选择对老年人房室结慢径消融术的成功率、复发率以及房室传导阻滞并发症有何影响，目前国内外文献报道较少，我们结合临床治疗的病例进行探讨。We analyzed retrospectively the clinical and electrophysiological data of 240 patients with paroxysmal AVNRT who had accepted electrophysiological studies and radiofrequency ablation treatment.Compared with the young group,the RP′interval in AVNRT and the width of SII were significantly longer in the elderly group,which had statistical significance（P0.05）.The reaction of ablation discharge：the majority of elderly had moderate intensity or weak reaction,however,the younger often had strong reaction.In the slow pathway blocking rate：the younger was 72.5%,and the elderly was 87.5%,which had statistical significance（P0.05）,but there were no significant difference in the surgical success rate,the recurrence rate and the incidence of atrioventricular block.
