射频消融术治疗房室结折返性心动过速483例临床分析

目的：回顾性分析射频消融术治疗房室结折返性心动过速（AVNRT）483例的疗效及安全性。方法：所有病例均经心内电生理检查，明确诊断AVNRT后，再分为A组：慢快型、B组：快慢型、C组：慢慢型三型，以中下位法结合电解剖法行射频消融术，统计总的和三组的消融成功率、并发症发生率、死亡率、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2.27％ ，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无统计学差异，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：射频消融术治疗房室结折返性心动过速总的成功率高，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。

Treatment of atrioventricular nodal reentrant tachycardia with radiofrequency ablation in 483 patients

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 ...
