What does early deceleration mean in pregnancy?
Subsequently, one may also ask, what causes early decelerations?
Early decelerations are caused by fetal head compression during uterine contraction, resulting in vagal stimulation and slowing of the heart rate.
Beside above, what causes late decelerations in pregnancy? They are caused by decreased blood flow to the placenta and can signify an impending fetal acidemia. Typically, late decelerations are shallow, with slow onset and gradual return to normal baseline. The usual cause of the late deceleration is uteroplacental insufficiency.
Similarly one may ask, are early decelerations normal?
Decelerations are temporary drops in the fetal heart rate. There are three basic types of decelerations: early decelerations, late decelerations, and variable decelerations. Early decelerations are generally normal and not concerning. Late and variable decelerations can sometimes be a sign the baby isn't doing well.
What do variable decelerations indicate?
Variable decelerations have no fixed time relationship to uterine contractions. Therefore, the pattern of decelerations changes from one contraction to another. Variable decelerations are usually caused by compression of the umbilical cord and do not indicate the presence of fetal distress.
