摘要 探讨射频导管消融(RFCA)在治疗儿童快速性心律失常中的临床价值，采用RFCA治疗儿童室上性心动过速(SVT) 93例、特发性室性心动过速(IVT) 7例。结果：SVT消融成功率为91.4%，右侧旁道消融成功率低于左侧旁道及房室结慢径路消融的成功率(81.8% vs 96.8%及96.6%；P均<0.05)。随访37.3±20.7个月，8例复发，其中2例发作次数较术前减少，口服普罗帕酮可预防发作，另6例再次消融成功。IVT首次消融均成功，随访19.5±10.3个月，2例复发，均再次消融成功。全组无并发症发生。结果提示RFCA治疗儿童快速性心律失常是有效的、安全的。

Abstract To investigate the clinical value of radiofrequency catheter ablation(RFCA) for tachyarrhythmias in children,RFCAWas used for supraventricular tachycardia(SVT) in 93 children,idiopathic ventricular tachycardia (IVT) in 7 children.Results:Thesuccess rate of ablatingsVTWas 91.4%.Thesuccess rate of ablating right accessory pathwayWas lower than that of left accessory pathway andslow pathway (81.8% vs 96.8%,96.6%,P<0.05,respectively).Eight cases recurred,and 6 casesWere undergonesuccessful ablation again during a mean follow-up of 37.3±20.7 months.The initial ablationWeresuccessful in 7 casesWith IVT.Two cases recurred andWere undergonesuccessful ablation again during a mean follow-up of 19.5±10.3 months.The result ssuggest that RFCA for tachyarrhythmias in children is effective andsafe.
