摘要

目的:观察导管射频消融治疗室性心动过速的疗效及安全性。方法:33例室性心动过速患者进行了电生理检查和射频消融治疗

特发性室性心动过速30例

致心律失常右室性心肌病3例。特发性室性心动过速采用起搏标测和（或）激动标测

致心律失常右室性心肌病采用Carto系统标测。平均随访28±17月

观察射频消融治疗效果及安全性。结果:①射频消融治疗即刻成功率90.9%（30/33）

失败3例为特发性室性心动过速;远期成功率87.9%（29/33）

复发1例为致心律失常右室性心肌病;②所有成功病例在消融过程中均有心室反应;③无任何并发症发生。结论:射频消融治疗室性心动过速的疗效及安全性高;消融过程中出现心室反应可能是成功的指标。

Abstract

Objective:To investigate the efficacy and safety of catheter radiofrequency ablation for ventricular tachycardia.Methods:Thirty-three patients with ventricular tachycardia were performed electrophysiologic study and radiofrequency ablation.Thirty cases with idiopathic ventricular tachycardia underwent pacemapping and/or activation mapping

and 3cases with arrhyththmogenic right ventricular cardiomyopathy underwent Carto system mapping.During the average follow-up of 28±17 months

acute successful rate and long-term successful rate of radiofrequency ablation were recorded

and safety was observed.Rsults:①For radiofrequency ablation

the acute successful rate was 90.9%(30/33)

and 3 cases without successful ablation were with idiopathic ventricular tachycardia;long-time successful rate was 87.9%(29/33)

and 1 case with arrhyththmogenic right ventricular cardiomyopathy reoccurred.②Ventricular responses were induced by radiofrequency ablation in all successful cases.③No complication occurred.Conclusions:Successful rate and safety of radiofrequency ablation for ventricular tachycardia were high;and the ventricular responses during ablation could be the predictors for successful ablation.
