本文报告327例心脏病患儿和250例健康儿童二维超声心动图与心电图对比研究。结果证明,心电图诊断左室肥大R_(v5)+S_(v1)符合率为74.4%,R_(aVF)为27.6%,R_Ⅱ+R_Ⅲ为9.0%,R_Ⅲ+肥S_I为2.6%;诊断右室肥大R_(v1)+S_(v5)为73.1%、R_(avR)为55.2%;诊断右房肥大为38.9%,左房大为34.8%。心电图诊断左室肥大的假阳性率为1.2%,右室肥大的假阳性率为0.8%,心房肥大无假阳性。可见心电图诊断心脏肥大阳性率不高。
This article reports 327 cases of heart disease and 250 healthy children two-dimensional echocardiography and ECG comparative study. The results showed that the coincidence rate of ECG RV_ (v5) + S v1 was 74.4%, 27.6% for aVF, 9.0% for R_II + R_III and 2.6% for R_III + S_ (v1). The diagnosis of right ventricular hypertrophy The R_ (v1) + S_ (v5) was 73.1% and the R_ (avR) was 55.2%. The diagnosis of right atrium was 38.9% and the left atrium was 34.8%. The false positive rate of ECG diagnosis of left ventricular hypertrophy was 1.2%, the false positive rate of right ventricular hypertrophy was 0.8%, and there was no false positive in atrial hypertrophy. Visible ECG diagnosis of cardiac hypertrophy positive rate is not high.
