Abstract：Objective To investigate the effectiveness of application of overlapped M-mode sonography and color Doppler Ultrasound images in diagnosis of fetal cardiac arrhythmia. Methods M-mode sonography and color Doppler ultrasound images of pregnant women who were treated in the hospital from January 2010 to June 2014 were overlapped so as to collect the number and type of fetuses with cardiac arrhythmia and make follow-ups for different types of fetal cardiac arrhythmia. Results Altogether 115 fetuses were revealed with cardiac arrhythmia, including 48 cases of atrial premature contraction, 2 cases of ventricular premature contraction, 35 cases of sinus tachycardia, 3 cases of supraventricular tachycardia, 4 cases of fetal atrial flutter, 1 case of atrial fibrillation, 13 cases of sinus bradycardia, 3 cases of blocked atrial bigeminy as well as 6 cases of atrioventricular conduction block. Among the 115 fetuses, there were 14 fetuses accompanied with both cardiac arrhythmias and cardiac structural abnormalities; 12 fetuses were accompanied with heart failures and 6 cases accompanied with hydrops. Significant differences were seen between the prognosis for different types of fetal cardiac arrhythmia. Conclusion The overlapped M-mode sonography and color Doppler ultrasound images could make accurate diagnosis and classification of fetal cardiac arrhythmia, which was of greatly clinical significance．
