【摘要】 目的观察射频消融术治疗房室结折返性心动过速(AVNRT)的疗效及安全性。方法对483例行射频消融术治疗的AVNRT患者的临床资料进行回顾性分析。所有病例均经心内电生理检查,明确诊断AVN-RT后,再分为慢快型、快慢型、慢慢型三型,以中下位法结合电解剖法行射频消融术,统计总的和3组的消融成功率、并发症发生率、病死率、复发率等。结果射频消融术治疗AVNRT总的成功率99.4%,并发症发生率2.28%,复发率1.45%,无死亡病例。慢快型、慢慢型、快慢型三型一次成功率差异无统计学意义,快慢型、慢慢型较慢快型并发症发生率、复发率为高,差异有统计学意义。结论射频消融术治疗AVNRT总的成功率高,并发症少,复发率低。但快慢型、慢慢型较慢快型并发症发生率、复发率为高,须引起足够重视。更多还原

【Abstract】 Objective To evaluate the efficacy and safety of radiofrequency ablation in treatment of atrioventricu-lar nodal reentrant tachycardia(AVNRT).Methods Retrospective analysis was carried out on 483 electrophysiologically proven AVNRT patients,who were divided into 3 groups: Group A(slow-fast type),Group B(fast-slow type) and Group C(slow-slow type).Radiofrequency ablation was performed on each patient.The success rate,recurrence rate,and incidence rates of complication and mortality were recorded.Results The success rate,recurrence rate and inci-dence of complication were 99.4%,1.45% and 2.28%,respectively.Furthermore,no death was recorded.No signifi-cant difference was observed in success rate among the 3 groups,while significant higher complication incidences and re-currence rates were revealed in Group B and C than those in Group A(P < 0.05).Conclusion Radiofrequency ablation for AVNRT treatment provides high success rate with low incidence of complications and relapses.However,the relatively higher complication and recurrence rates in fast-slow type and slow-slow type AVNRT should be emphasized.更多还原
