Abstract:
Purpose To probe into the value of M-mode echocardiography and spectral Doppler echocardiography in diagnosing fetal atrial premature beats.Materials and Methods Echocardiography examinations were given to the seventy-three fetuses around 16-40 gestational weeks which were found suffering from fetal arrhythmia in the clinical examinations by using M-mode echocardiography and spectral Doppler. Thirty-two of them were screened out with fetal atrial premature beats, and their ultrasonic cardiograms were analyzed. The follow-up visits were later conducted.Results Among the thirty-two cases with fetal atrial premature beats, fourteen were attacked frequently, and the other eighteen were attacked accidentally. Two cases were documented with muscular ventricular septal defect. Apart from two missing cases, the rest thirty cases were found to be recovered from arrhythmia before or after birth in the follow-up visits. The disappearance rate of atrialpremature beats in the fetuses attacked frequently by the disease before birth was clearly lower than that in those attacked accidentally (P<0.05). Muscular ventricular septal defect in the two cases were found closed after birth. Conclusion M-mode echocardiography and spectral Doppler echocardiography, as non-invasive imagining techniques to take antenatal examination of fetal arrhythmia, have advantages such as reliable, direct, convenient and can be used repetitively, therefore can provide important information for clinical treatment and prognosis.
