MATERIAL AND METHODS During four years 94 pregnancies with fetal cardiac arrhythmia were examined. In all of them fetal ECG was recorded and an examination of the fetal anatomy with special concern to the fetal heart was performed using real-time ultrasound. In 52 pregnancies fetal phonocardiogram was recorded and in 48 pregnancies fetal blood flow in the descending aorta and in the inträäbdominal part of the umbilical vein was measured by means of a non-invasive ultrasonic method combining real-time ultrasonography and pulsed Doppler technique (1).
