Diagnosing fetal arrhythmia with pulse Doppler combined with electrocardiographic thinking / 中国医学影像技术

ABSTRACT

Objective To investigate the feasibility of pulse Doppler combined with electrocardiographic thinking for diagnosis of fetal arrhythmia. Methods Sixty-five fetuses with arrhythmia were examined with prenatal ultrasound. Pulse Doppler spectrum of pulmonary arteries and pulmonary veins were ontained and anlyzed with electrocardiographic thinking, and different kinds of fetal arrhythmia were diagnosed and classified. Results Among the 65 fetuses, 12 were found with sinus bradycardia, 8 with sinus tachycardia, 5 with supraventricular tachycardia, 28 with atrial premature beat, 7 with premature ventricular and 5 with atrioventricular block. Conclusion Pulse Doppler combined with electrocardiographic thinking plays an important role in the diagnosis and classification of fetal arrhythmia.
