Abstract
In the course of routine, two-dimensional ultrasonic echoscopy, echograms have been obtained which show the outline of the fetal heart and interventricular septum. Measurements of the echograms show the fetal heart to occupy 21% of the cross-sectional area of the chest at its widest transverse diameter and to occupy 52% of the transverse diameter of the chest at the same level.
The ratio of the tranverse diameter of the left ventricle to that of the right (L.V. ÷ R.V.) is 1.23. The fetal heart grows at the same rate as the fetal chest in the last 8 weeks of pregnancy.
