Fetal heart rate was monitored by continuous cardiotocography in 67 patients who were subjected to standard epidural block. In 43% of cases a deterioration in the fetal heart rate pattern was observed. The abnormal heart rate usually responded to conservative treatment. In 3 cases caesarean section was necessary. The deterioration of the fetal heart rate was usually associated with maternal hypotension.
