摘要
目的探讨双多普勒超声在检测胎儿房性期前收缩中的应用价值。方法应用彩色多普勒超声对7013例胎儿进行常规检查，发现有胎儿心律失常者行双多普勒超声检查，同步记录肝静脉（HV）、降主动脉（DAo）血流频谱。比较20例正常心律胎儿常规多普勒及双多普勒检测时间。结果检出房性期前收缩胎儿28例，包括房性期前收缩伴下传14例，房性期前收缩伴未下传8例，房性期前收缩部分下传部分未下传6例，所有病例未发现合并严重先天性心脏畸形。26例房性期前收缩胎儿均于晚孕期转为正常窦性心律，2例胎儿于产后3d转为正常窦性心律。正常胎儿的心律双多普勒超声检测时间明显少于常规多普勒（P〈0．05）。结论双多普勒超声检测胎儿房性期前收缩简便、快速，可用于精确诊断胎儿房性期前收缩。
Objective To evaluate the value of dual Doppler ultrasonography in the diagnosis of fetal atrial extrasystoles. Methods Seven thousands and thirteen fetuses were examined by fetal echocardiography. If fetal arrhythmias were found, information of pulsed wave Doppler signals in hepatic vein （HV） and descending aorta （DAo） using dual Doppler were colleted simultaneously. The detected times were compared between using general Doppler and dual Doppler in 20 cases. Results On dual Doppler examination,28 of the fetuses showed signals of atrial extrasystoles, 14 fetuses atrial extrasystoles conducted to ventricle,8 fetuses atrial extrasystoles non-conducted to ventricle,6 fetuses with part of the extrasystoles conducted to ventricle and part of the extrasystoles non-conducted to ventricle. No case had congenital heart disease. Twenty-six fetuses with atrial extrasystole were converted to normal rhythm within the third trimester of pregnancy, and the others; were converted to normal rhythm during the first 3 days postnatally. The detected time of dual Doppler was shorter than that of general Doppler（ P〈0.05）. Conclusions Dual Doppler ultrasonography of simultaneous recordings in HV and DAo is an easy, rapid method of assessing fetal atrial extrasystoles,whieh should allow precise diagnosis of atrial extrasystole.
