M型超声心动图结合房室梯形图诊断胎儿心律失常的应用价值

Application value of M-mode echocardiography combined with atrioventricular ladder diagram in the diagnosis of fetal arrhythmia

目的 探讨M型超声心动图结合房室梯形图诊断胎儿心律失常的临床应用价值。方法 选取经我院产前超声检查诊断为胎儿心律失常的孕妇165例,应用M型超声心动图取样线获取胎儿房室壁、房室瓣及半月瓣的活动曲线,结合房室梯形图诊断胎儿心律失常类型。结果 165例心律失常胎儿中,M型超声心动图结合房室梯形图诊断房性早搏76例(46.1%),窦性心动过速43例(26.1%),窦性心动过缓22例(13.3%),房室传导阻滞9例(5.5%),室上性心动过速8例(4.8%),室性早搏6例(3.6%),心房扑动1例(0.6%)。结论 M型超声心动图结合房室梯形图诊断胎儿心律失常简便、直观,能明确胎儿心律失常类型,具有较好的临床应用价值。

Objective To investigate the clinical application value of M-mode echocardiography combined with atrioventricular ladder diagram in the diagnosis of fetal arrhythmia.Methods A total of 165 pregnant women diagnosed with fetal arrhythmia by prenatal ultrasonography in our hospital were selected. The activity curves of fetal atrioventricular wall,atrioventricular valve and semilunar valve were obtained by M-mode echocardiography sampling line,and the type of fetal arrhythmia was diagnosed by combining atrioventricular ladder diagram.Results Among the 165 fetuses with arrhythmia,there were 76 cases(46.1%)of atrial premature beats,43 cases(26.1%)of sinus tachycardia,22 cases(13.3%)of sinus bradycardia,9 cases(5.5%)of atrioventricular block,8 cases(4.8%)of supraventricular tachycardia,6 cases(3.6%)of ventricular premature beats,1 case of atrial flutter(0.6%) by M-mode echocardiography combined with atrioventricular ladder diagram.Conclusion M-mode echocardiography combined with atrioventricular ladder diagram is simple and intuitive to diagnose fetal arrhythmia,which can identify the type of fetal arrhythmia and has good clinical value.
