baby's heart rate does not get slower (decelerate) and stay slow after the
contraction (late decelerations). Note: There may be a
few times during the test when your baby's heart rate decelerates, but it
doesn't stay slow so it is not a problem.

occur during a 10-minute period of nipple stimulation or oxytocin infusion and
there are no late decelerations in your baby's heart rate, your baby is
expected to be able to handle the stress of labor.
Abnormal test results are called positive.
baby's heart rate gets slower (decelerates) and stays slow after the
