摘　　要：导管射频消蚀术（ＲＦＣＡ）治疗特发性室性心动过速（ＩＶＴ）５例。其中ＩＶＴ起源于左室间隔区３例，右室流出道２例。４例在ＩＶＴ发作中于室内标测到较体表ＱＲＳ波提早３０～５０ｍｓ的局部电位，在此点给予射频电流，ＩＶＴ即刻终止；１例ＩＶＴ行起搏标测，在左室中间隔区标测到与ＩＶＴ时１２导联相同的ＱＲＳ波群，在该部位给予射频电流。全部病例术后停用各种抗心律失常药物，随访１～４个月，无ＩＶＴ复发，无并发症，表明ＲＦＣＡ是根治ＩＶＴ安全有效的方法。Abstract Five patients (three women and two men; mean age 40, range 14 to 59 years) with idiopathic sustained ventricular tachycardia (VT) resistant to medical antiarrhythmic managemant were successfully treated by radiofrequency (RF) catheter ablation technique. Careful endocardial mapping showed that the VT originated from the left septal area in three patients, and from right outflow tract in two. RF currents were delivered in four cases to the area where an earliest onset of endocardial activation proceding the QRS complex during VT (ranged between-30 and -50ms) can be recorded, which resulted in an immediate termination of tachycardia. In one patient , whose left VT became noninducible after terminated by mechanical stimulus from the catheter manipulation , the ablation was guided by pacemapping method. No complications occurred during the ablation procedure. Thereafter, in all patients, the clinical tachycardias were no longer inducible by programmed stimulation and isoproperanol infusion. During a follow-up period of one to four months, all the patients are well and free from any tachyarrhythmias on no medication.
