【摘要】 采用经导管电击治疗药物效果不佳的频发持续性室性心动过速5例。病灶定位主要依靠起搏标测结果。电击能量每次150～250J,总能量600～800J。随访19～41(平均26.8)月,4例无复发,其中2例巳停药;另1例于术后4个月室性心动过速复发,但心率较术前明显减慢。本组有限的病例提示:成功的经导管电击治疗室性心动过速远期疗效令人鼓舞。更多还原

【Abstract】 Transcatheter electrical ablation was performed in 5 patients, none of them showed clinical effectiveness for treatment of antiarrhythmic drugs, with recurrent sustained ventricular tachycardia (VT). The localization of ventricular ectopic focus mainly depended upon the results of pace mapping. Energy used for each transcatheter electrical ablation (TEA) was usually 150-250J and the total energy was 550J to 800J respectively for each patient. No recurrence of VT was observed in 4 cases during 19 to 41 (mean 26.8) months of follow-up period, two of them without adminstration of drug. Sustained VT relapsed 4 months after ablation in one case, however, heart rate during VT was much slower than before. Our experience suggests that long-term effectiveness of TEA for treatment of drug-resist VT is inspiring.更多还原
