Summary: Between 1981 and 1986, 9,840 women were monitored by antepartum nonstressed cardiotocography (CTG). A satisfactory fetal reserve pattern was detected in 91%, a reduced reserve pattern in 8% and a critical reserve pattern in 1%. The incidences of fetal growth retardation, Apgar score < 6 at 1 minute, perinatal mortality and Caesarean section all increased significantly (p < 0.001) as the degree of cardiotocographic fetal reserve worsened. Intrauterine growth retardation and/or low urinary oestriol excretion was associated with a highly significantly increased incidence of abnormal CTG traces (14.2%, p < 0.001). A satisfactory fetal reserve pattern on cardiotocography was a reliable predictor of fetal well‐being, since after exclusion of lethal malformations, the perinatal mortality rate in those patients monitored within 7 days of delivery was 3/1,000.
