摘要:
目的: 观察房室结折返性心动过速（AVNRT）的慢径消融终点与复发的联系。方法： 534个慢-快型AVNRT患者行慢径消融治疗，观察A型终点（彻底消融慢径，房室结无跳无折）和B型终点（残留慢径有或无1~3心房回波，不能诱发AVNRT）与AVNRT复发的联系及对房室结传导的影响。结果： ①A型复发5例（1.2%），B型复发11例（9.4%），差异有统计学意义（P<0.05）。②A型终点房室结前传文氏周期（Wen-AVN）、快径前传有效不应期和房室结双径路（DAVNP）的跳跃增值缩短，B型快径前传有效不应期和房室结双径路的跳跃增值缩短，A型有效不应期的缩短明显大于B型。结论： A型终点的复发率明显低于B型终点；只要改变房室传导功能，不能诱发心动过速，B型终点仍然是有效、可靠的消融终点。
Abstract:
AIM: To study the relationship between endpoints of slow atrioventricular nodal pathway ablation and recurrence in patients with atrioventricular nodal reentrant tachycardia (AVNRT). METHODS: Slow pathway radiofrequency ablation was performed in 534 patients with slow-fast AVNRT and the effect of endpoint was observed in type A (complete disappearance of slow pathways and inducible AVNRT with no jumping phenomenon and AVN echo) and type B (residual slow pathway conduction without inducible AVNRT). RESULTS: Endpoint A recurred in 5/415 cases (1.2%) and endpoint B recurred in 11/117 cases (9.4%) with significant differences between them. AV1∶1CL, FP-ERP and △A2H2 of endpoint A became shorter and FP-ERP and △A2H2 of endpoint B became shorter, but △FP-ERP of endpoint A was longer than endpoint B. CONCLUSION: The recurrence rate of type A is lower than that of type B. Type B can be an effective and safe ablation endpoint with good AV conduction and no inducible AVNRT.
