我院于1993年4月以来为4例室上性心动过速的病人进行了心内射频消蚀术(RFCA),3例为A 型隐匿性预激,1例为房扑,现将心房扑动(房扑)RFCA 情况介绍如下。病历摘要患者女、55岁,高血压病史10余年,最高达24/14.5kPa,反复发作心动过速,伴昏厥10余次,近半年发作频繁,甚至每日大便均可诱发,并常致晕厥。体查:超体重型、面颊潮红,口唇轻度紫绀,心尖部S_1正常,肺动脉瓣区可闻及Ⅱ级收缩期杂音,S_2亢进且固定分裂,三尖瓣区可闻及流量性杂音。X 线胸片,扇形超声均示主动脉结增大,全心增大,房间隔缺损(继发孔型)。ECG 示房扑2:1、3:1传导,F 波在Ⅱ、Ⅲ、arF 导联呈直立状。心室率100～110次/分,心动过速时呈1:1传导,心室率可达256次/分;伴完全性右束枝传导
Four cases of supraventricular tachycardia were performed RFCA in our hospital since April 1993. Three cases were type A occult pre-excitation and one case was atrial flutter. Flutter (atrial flutter) RFCA situation is as follows. Patient history, 55 years old, history of hypertension more than 10 years, up to 24 / 14.5kPa, recurrent tachycardia, with fainting more than 10 times, frequent seizures in the past six months, and even daily stool can be induced and often cause syncope . Physical examination: super body weight, cheek flushing, lips mild cyanosis, apical S_1 normal, pulmonary valve area can be heard and Ⅱ systolic murmur, S_2 hyperthyroidism and fixed division, the tricuspid valve area can be heard and flow murmur. X-ray, fan-shaped ultrasound showed increased aortic node, total heart enlargement, atrial septal defect (secondary orifice). ECG atrial flutter 2: 1,3: 1 conduction, F wave in Ⅱ, Ⅲ, arF lead was erect. Ventricular rate of 100 ~ 110 beats / min, tachycardia was 1: 1 conduction, ventricular rate up to 256 beats / min; with complete right bundle branch conduction
