摘　　要：目的探讨心电图诊断对房室间隔缺损的临床应用价值。方法对照分析120例房室间隔缺损患儿(部分型、过渡型、完全型各40例)和177例其他先天性心脏病(紫绀型57例、房间隔缺损61例、室间隔缺损59例)(对照组)的心电图表现。结果房室间隔缺损患儿同时出现P-R间期延长、不完全性右束支传导阻滞、左前分支阻滞的阳性率明显高于对照组,但3种不同类型的房室间隔缺损间心电图表现差异均无显著性意义。结论心电图同时出现P-R间期延长、不完全性右束支传导阻滞和左前分支阻滞高度提示房室间隔缺损存在,结合临床可作出初步诊断,但心电图对房室间隔缺损的分型诊断无意义。Objective To explore clinical value of ECG in diagnose of atrioventricular septal defect (AVSD). Methods ECG was analyzed in 120 patients with AVSD (40 partial AVSD, 40 transitional AVSD and 40 complete AVSD)and in 177 patients with other cardiac lesions(57 cyanotic heart disease, 61 atrial septal defect and 59 ventricular septal defect). All diagnosis was confirmed by prolonged P-R interval echocardiography and catheterization examination. Results Compared with control group, positive rate of prolonged P-R interval, prolonged P-R interval,incomplete right bundle branch block and left anterior fascicular block in AVSD patients is significantly increased. Difference of ECG among three types of AVSD is not significant. Conclusion AVSD should be suggested when ECG showed incomplete right bundle branch block, left anterior fascicular block and prolonged P-R interval, though ECG is not sensitive in defining type of AVSD. 
