Abstract:
Objective To investigate a new method for detecting fetal cardiac arrhythmia.Methods Used two kinds of superposition:①left 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 heat,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.
