Electrode catheter ablation was used to treat 11 distinct types of sustained ventricular tachycardias in eight patients. Rigid electrophysiological criteria were used to identify five left and five right ventricular arrhythmogenic sites; one of them gave rise to tachycardia with two distinct configurations. A single R-wave-synchronised 250 or 150 J cathodal shock was delivered at each site. One patient had mildly symptomatic episodes of sustained ventricular tachycardia during the first four days after the shock--there were no other complications. At discharge none of the patients was taking antiarrhythmic drugs. They were followed for 8-20 months (mean 14). Ablation abolished five of the 11 ventricular tachycardias. There was no recurrence in three of the eight patients. In two patients identical ventricular tachycardias recurred because the identification of the arrhythmogenic site was incorrect.
采用电极导管消融术治疗8例患者的11种不同类型的持续性室性心动过速。采用严格的电生理标准确定5个左心室和5个右心室心律失常起源部位；其中1个部位引发了两种不同形态的心动过速。在每个部位给予单次R波同步的250或150 J阴极电击。1例患者在电击后的头4天出现轻度症状性持续性室性心动过速发作，无其他并发症。出院时，所有患者均未服用抗心律失常药物。对他们进行了8 - 20个月（平均14个月）的随访。消融消除了11种室性心动过速中的5种。8例患者中有3例未复发。2例患者出现相同的室性心动过速复发，原因是心律失常起源部位的识别有误。
