Summary: Heart function in 19 normotensive and 27 hypertensive pregnant women was studied by a new technique for measuring systolic time intervals and by standard methods for measuring haemodynamic variables. In the hypertensive pregnant women, although heart rate and blood volume were not altered significantly, cardiac output, stroke volume, left ventricular work and total peripheral resistance were all increased and were accompanied by slightly less efficient cardiac contractility compared with findings in normotensive pregnant women.
