Summary Continuous recordings of maternal and fetal heart rate were made in 30 antenatal patients during simulated abdominal radiography in late pregnancy. Transient changes in fetal heart rate occurred in 43 per cent of patients in the supine position compared with 27 per cent in the prone position. Transient increases of maternal heart rate occurred in 37 per cent of patients. There was no evidence of revealed or concealed caval occlusion.
