摘要 目的:探讨射频消融房室旁路引起的室上性心动过速阻断旁路时间与室上速复发的关系,以降低术后复发率。方法:对接受导管消融的179例房室旁路引起的阵发性室上性心动过速患者进行回顾性分析。结果:接受射频消融治疗的179例(187条旁路)患者,一次性消融成功176例(183条旁路),成功率达98.3%(176/179)。消融成功病例随访3个~24个月,复发6例,其中持续放电5 s内阻断旁路者无复发病例;6 s^10 s内阻断旁路者复发2例,复发率2.6%(2/75);11 s^15 s内阻断旁路者复发4例,复发率44.4%(4/9)。6例复发病例再次消融时,阻断旁路放电时间均在5 s内,随访无复发。旁道在5 s内、10 s内和15 s内阻断相比较,复发率有显著性差异(P<0.05)。结论:房室旁路引起的室上性心动过速阻断旁路放电时间越长复发率越高,有效放电时间与成功率相关。
