导管射频消融治疗房室结折返性心动过速(附82例报告)

The Radiofrequency Catheter Ablation of Atrioventricular Node Reentrant Tachycardia (Report of 82 Cases)

８２例病人经导管射频消融（ＲＦＣＡ）治疗房室结折返性心动过速（ＡＶＮＲＴ），成功率９６．３％，无１例发生Ⅲ度房室传导阻滞（ＡＶＢ）。随访２～３６个月，复发１例。ＲＦＣＡ治疗ＡＶＮＲＴ是安全有效的方法。保持消融导管稳定、间断放电并连续监测Ｘ线影像和心电变化是避免Ⅲ度ＡＶＢ发生的关键。

patients with atrioventricular node reentrant tachycardia (AVNRT) were treated with radiofrequency catheter ablation (RFCA). The success rate was 96.3%. No patient developed third degree AV block (Ⅲ°AVB). One patient recurred during 2 to 36 months of follow up. In conclusion, RFCA for AVNRT is effective and safe. In order to avoid inducing Ⅲ°AVB, it′s critical to keep catheter stable and pay attention to X ray and electrocardiograph during ablation. \ \
