Fetal Cardiac Activity
Abstract
Improvement in both real-time two-dimensional (2D) ultrasonic scanners and M-mode recording systems has led to increasing research into fetal cardiovascular dynamics [1, 2, 3]. Recently, the introduction of pulsed Doppler systems of low MHz frequency has opened up the possibility of studying flow velocity in the umbilical vein and abdominal part of the descending aorta [4] during the last trimester of pregnancy. The studies carried out at our Ultrasound Laboratory have been focussed lately on the geometry and functional behaviour of the cardiac ventricles, as well as the flow distribution to the umbilical vein and descending aorta relative to total cardiac output.
