报道小儿室性心动过速经射频消蚀成功.6例患儿男4例、女2例,平均年龄9.5岁.病史3个月～3年.药物疗效不满意.1例为右室流出道室速,3例为左后分支型室速,2例为左前分支型室速.临床检查确诊无器质性心脏病的特发性室速.分别采用起搏标测法和(或)激动顺序标测法标测室速激动起源点,用10～30瓦功率射频消蚀成功.对3例左后分支型室速,首先采用束支改良法射频消蚀亦取得成功.无并发症发生.结果表明,对于小儿特发性室速射频消蚀是安全有效的方法
Report of children with ventricular tachycardia by radio frequency eradication success .6 cases of male 4 patients, 2 females, mean age 9.5 years. History of 3 months to 3 years. Drug efficacy is not satisfied .1 cases of right ventricular outflow tract Ventricular tachycardia, left ventricular tachycardia in 3 cases, left ventricular tachycardia in 2 cases, idiopathic ventricular tachycardia without organic heart disease confirmed by clinical examination, Sequential mapping method was used to detect the origin of ventricular tachycardia, which was successfully eroded by 10 ~ 30 Watt RF radiosurgery.Among 3 cases of left posterior branch ventricular tachycardia, RF beam eradication by beam bundle modification was also successful. The results show that it is a safe and effective method for RFI of pediatric idiopathic ventricular tachycardia
