摘　　要：目的探索利用M型超声与彩色多普勒图像叠加法记录并诊断胎儿心律失常。方法应用两种叠加方式：①左室流出道血流一右心房壁运动曲线叠加法；②左室流出道-左室流入道彩色血流信号与M超叠加法，共检出胎儿心律失常167例。结果167例中房性期前收缩84例（50．2％），室性期前收缩39例（23．3％），一过性窦性心动过缓23例（13．7％），窦性心动过速12例（7．1％），Ⅱ度房室传导阻滞4例（2．3％），完全性房室传导阻滞2例（1．2％），心房颤动3例（1．8％）。结论M型超声与彩色多普勒叠图像叠加法诊断胎儿心律失常方法简便，结果可靠。Objective To investigate a new method for detecting fetal cardiac arrhythmia. Methods Used two kinds of superposition： ① left ventricular outflow tract color flow image with right atrium wall motion curves superposition, ②left ventricular outflow tract color flow image with left ventricular inflow tract colour flow image superposition, 167 cases of fetal arrhythmia were detected. Results Among them,84 fetuses with atrial premature beat,39 with ventricular premature beat,23 with temporal sinus bradycardia, 12 with sinus tachycardia, 4 with II° atrioventricular block （AVB）, 2 with III° AVB, 3 with atrial fibrillation. Conclusions Using superposition of M-mode echocardiagraphy with color Doppler imaging to diagnose fetal cardiac arrhythmia is easier and more accurate.
