WebEach has its own features and clinical significance. In addition, a fetus may demonstrate combined decelerations (for example, a severe variable deceleration with a late deceleration component.) Early Decelerations Early decelerations are periodic slowing of the fetal heartbeat, synchronized exactly with the contractions.
