The diagnosis value of pulse Doppler echocardiography for fetal arrhythmias
Abstract：Objectives To investigate the diagnosis value of pulse Doppler echocardiography in prenatal diagnosis for fetal arrhythmia .Methods One hundred and thirty-six fetuses with arrhythmia were examined by prenatal fetal echocardiography .The different kinds of fetal arrhythmias were diagnosed and classified according to pulse Doppler flow inaging frequency spectrum in pulmonary arteries and pulmonary veins .Results One hundred and thirty-six fetus with arrhythmia were found by pulse Doppler echocardiography ,including 79 cases of atrial premature beats ,27 cases of ventricular premature beats,24 cases of tachycardia (13 cases of sinus tachycardia and 11 cases of supraventricular tachycardia ),2 cases of sinus bradycardia (1 cases of single ventricle and 1 cases of complete atrioventricular septal defect ,both were induced labor ),and 4 cases of atrial flutter .The rest cases were not associated with congenital cardiovascular malformations or other deformities . Echocardiography showed there was no obvious cardiac abnormality or arrhythmia after birth .Conclusion The pulse Doppler echocardiography to detect flow inaging frequency spectrum in pulmonary arteries and pulmonary veins can diagnose and classify fetal arrhythmia quickly and accurately .
