Summary

The relationship between the continuous fetal heart rate pattern in the first stage of labour and the one-minute Apgar score of the newborn was examined in 714 patients. The highest incidence of fetal depression (one-minute Apgar score less than 7) was observed with the late deceleration pattern and with variable deceleration associated with an abnormal baseline. Variable deceleration with a normal baseline and loss of beat-to-beat variation, both complicated and uncomplicated, were associated with infants with a low Apgar score to a greater degree than were the other patterns.
