Or a handheld Doppler ultrasound device may be used to check the heart rate every 15 minutes during early labor and after each contraction during late labor.

If no drug was used to stimulate contractions, the woman may be given a drug that can slow labor (such as terbutaline, given by injection) to stop or slow the contractions.
