摘要
经导管射频消融治疗8例顽固性室性心动过速。术中以心室起搏标测定位,成功5例,失败3例,无并发症。
Eight consecutive patients (6 males and 2 females, mean age 35 of (15-55) years underwent transvenous radiofrequency catheter ablation (RFCA) of ventricular tachycardia (VT). All of the patients had recurrent, symptomatic episodes of sustained (duration≥30 sec) monomorphic VT resistant to antiarrhythmic drug therapy. One patient had idiopathic dilated cardiomyopathy, while the others had no documented cause. The ectopic focus with VT was located by pace mapping. The configuration of QRS from pace mapping should be in complete accordance with that of spontaneous VT 12-lead ECG. 5/8 patients had been successfully treated with RFCA.
