摘　　要：目的通过分析40例小儿三尖瓣下移畸形的心电图,探讨小儿三尖瓣下移畸形的心电图特点。方法分析40例三尖瓣下移畸形的心电图变化;并与其它50例房间隔缺损、50例各种紫绀型先天性心脏病心电图比较;并对三尖瓣下移畸形组中不同心功能级别的患儿(Ⅰ～Ⅱ级、Ⅱ级以上)的心电图进行分析。结果右房大、右束支阻滞、一度房室阻滞、V1导联R′波电压低、右胸导联出现q波伴T倒置、B型预激综合征、阵发性心动过速史与对照组有显著性差异(p<0.01)。结论三尖瓣下移畸形的心电图特点对诊断和鉴别诊断有重要价值。Objective To explore the ECG features of Ebstein＇s anomaly in children. Methods Electrocar- diographic findings of 40 cases with Ebstein＇s anomaly were studied, compared with those of 50 cases with atrial septal defects and 50 cases with other cyanotic congenital heart diseases. ECG were also compared between cardiac function NYHA grade Ⅰ - Ⅱ and 〉grade Ⅱ in Ebstein＇s anomaly. Results There was significant difference in the incidence rate of the right arial enlargement, right bundle branch block, the first degree atrioventricular block, lower voltage of R＇ wave in lead V1, Q waves with inverted T waves in right precordial leads, the type B WPW syndrome and with paroxysmal of supraventricular tachycardias between the compared teams （p 〈0.01）. Conclusion ECG findings contribute to diagnosis and differential diagnosis of Ebstein＇s anomaly of the tricuspid valve in children.
