目的 总结提高射频消融术 (RFCA)治疗阵发性室上性心动过速 (PSVT)的安全性和成功率的经验。方法 回顾分析RFCA治疗PSVT 82例 ,包括房室间折返性心动过速 (AVRT) 4 8例 ,左侧旁道 2 5例 ,右侧旁道 2 0例 ,多条旁道 3例 ,房室结折返性心动过速 (AVNRT) 34例。均先行心内生理检查确定心动过速类型和消融靶点。结果 总成功率 98.78% (81/ 82例 ) ,总复发率 2 .4 7% (2 / 82例 ) ,AVRT和AVNRT各 1例 ,2例再次RFCA均获成功。82例无一例严重并发症和死亡。结论 根据设备条件严格掌握适应症 ,消融前系统电生理检查 ,避免先入为主 ,旁道消融靶点正确标测 ,放电中Ⅲ度房室传导阻滞 (AVB)的识别和消融终点正确判定是提高安全性和成功率的关键。
Objective To summarize the experience of improving the safety and success rate of radiofrequency ablation (RFCA) in the treatment of paroxysmal supraventricular tachycardia (PSVT). Methods A total of 82 patients with PSVT treated by RFCA were retrospectively analyzed, including 48 cases of atrioventricular reentrant tachycardia (AVRT), 25 cases of left bypass, 20 cases of right bypass, 3 cases of multiple bypass, Nodal reentrant tachycardia (AVNRT) in 34 cases. Prior to intracardiac physical examination to determine the type of tachycardia and ablation targets. Results The total success rate was 98.78% (81/82 cases), the total recurrence rate was 2.47% (2/82 cases), and one case of AVRT and AVNRT respectively. Two cases of RFCA were successful again. 82 cases without serious complications and death. Conclusions According to the equipment condition, the indications and pre-ablation system electrophysiological examination should be strictly followed to avoid preconception and the target of bypass ablation should be accurately identified. The correct identification of the third-degree atrioventricular block (AVB) and end-point of ablation in the discharge is to improve the safety Sex and the key to success rate.
