A nonstress test is used in pregnant women to evaluate the heart rate of a
developing baby (fetus). Normally, a developing baby's heart rate ranges from 100 to 160 beats per
minute, and it usually speeds up after the baby moves. If the heart rate is
faster or slower than this range or does not speed up after the baby moves, it
may mean that the baby is not doing well.
During the test:
A nonstress test usually takes about 30 minutes. It can be done in a
hospital or the doctor's office.
