摘　　要：评价特发性室性心律失常(室性心动过速和室性早搏)经导管射频消融治疗的临床疗效.10例患者(男4例,女6例),平均年龄42.5±17.3岁.其中频发室早5例,室速5例,采用激动标测法与起搏标测法相结合来确定起源点.4例心律失常位于右室流出道,5例位于左室中后间隔区,1例左室流出道室早位于左冠窦内.10例患者均获得良好效果,即刻成功率100%.随访期间(2～30个月)停用抗心律失常药物无心律失常复发.The result of radiofrequency catheter ablation for idiopathic ventricular tachyarrhythmias is evaluated. This study included 10 patients ( M/F 4/6,mean age 42.5±17.3 years; frequent ventricular ectopic beats in 5 patients and idiopathic ventricular tachycardia in other 5 patients). The site of origin was determined by activation mapping for the earliest endocardial activation, and by pace mapping for the exact QRS match between pacing and ectopic beat. Radiofrequency catheter ablation successed in all patients. No complications encountered. During the follow-up period(2～30 months), the patients were not given any antiarrhythmic drugs and were symptom-free in all of them. The results indicate that radiofrequency catheter ablation is an effective and safe treatment for idiopathic ventricular tachyarrhythmias.
