摘要
经导管射频消融治疗２０例室性心动过速，采用体表心电图初步定位和仔细的心内起搏标测与激动顺序标测定位相结合，成功１８例，成功率９０％，无并发症。
The surface electrocardiogram combined with endocardial pace mapping to locating ventricular ectopic focus,the radiofrequency cathater ablation of ventricular tachycardia was performed in 20 cases,18 cases were successfully ablated and no complications were noted.
