Summary. Fetal and early neonatal left and right ventricular cardiac geometry and left ventricular cardiac function were studied by M‐mode technique in a cross‐sectional study between 28 and 40 weeks of gestation ( n =227) and a longitudinal study from 24 h before until 48 h after delivery ( n =15). Antenatally both ventricles were geometrically uniform; there was a 3·2–3·4‐fold increase in left ventricular volume and a nearly 3‐fold increase in left ventricular stroke volume and cardic output. During the early neonatal period the right ventricular transverse diameter reduced in size; there was a further 1·1‐fold rise in left ventricular volume and a further 1·2–1·3‐fold rise in left ventricular stroke volume and cardiac output.
