摘　　要：目的：探讨超声心动图测定心脏轴变化在胎儿先天性心脏病（先心病）产前诊断中的临床意义。方法：采用LOGIQ7超声诊断仪检查2518例胎龄18—40w的先心病高危胎儿和90例正常胎儿，在心脏超声四腔观基础上测定胎儿心脏轴，并从多切面观察胎儿心内结构，以确定胎儿有无先心病。结果：共检出有先天性心脏病胎儿24例，其中心脏轴测定异常（大于75°）而四腔观无异常13例，其中四腔观异常而心脏轴测定无异常11例。结论：应用超声心脏轴测定在筛选胎儿先天性心脏病中可操作性强，且具有十分重要的临床意义。Objective： To investigate the clinical significance of cardiac axis determined by eehocardiography in the diagnosis of fetal congenital heart disease （CHD）. Method： 30229 for CHD were and 100 normal fetuses were examined by echocardiography. Cardiac axis was measured on four-chamber view and fetal cardic anatomical structure was examined in multiple views to determine CHD. Results： The 24 fetuses with CHD diagnosed by prenatal echocardiography. There is significant difference of caidiac axis between CHD group （51.4 ± 18.3 degree） and normal group （41.1 ±8.2degree, P〈0.01）. Conclusion： Cardiac axis play an key role in fetal echocardiographic screening for CHD.
