摘要
目的观察先天性心脏病的特征性圆钝尖角T波改变。方法对212例先天性心脏病的心电图的T波进行分析,并与低血钾心电图做比较。结果 212例先天性心脏病中有23例出现了圆钝尖角T波改变,发生率10.8%,见于室间隔缺损、房间隔缺损、复合型缺损、动脉导管未闭,多见于室间隔缺损,占60.9%,但复合型缺损发生率最高,为37.5%。圆钝尖角改变与低血钾改变明显不同,易于区分而成为先天性心脏病特征性改变。结论圆钝尖角T波改变是先天性心脏病的特征性改变,对先天性心脏病有很高的诊断价值。其机制是与左向右分流造成左右心室复极的不同步、合并右心室肥大有关。
Objective To observe the characteristic round and sharp-angled T wave's change of the congenital heart disease.Method analyse the 212 case inpaient electrocardiographics(ECG)with congenital heart disease,observe the T wave,and compare with the ECG of the Hypokalemic.Result 23 case are found the round and sharp-angled T wave among the 212 case's ECG with congenital heart disease,occupy 10.8% of the total.The round and sharp-angled T wave appear in the ventricular septal defect,atrial septal defect,compound type defect and patent ductus arteriosus.Frequently appear in the ventricular septal defect,occupy 60.9% of the all.but the generant rate is the highest in compound type defect.The round and sharp-angled T wave is remarkable differ from the ECG of the Hypokalemic.so it is the characteristic T wave's change of the congenital heart disease.Conclusion The round and sharp-angled T wave is the characteristic change of the congenital heart disease,it is of great value to diagnose the congenital heart disease.Mechanism is a blood shunt from left to right lead to desynchrony of the ventricular repolarization,also with the right ventricular hypertrophy.
