Fetal doppler heart

The doctor is more likely to use fetal heart rate monitoring when your pregnancy is high-risk. You may need fetal heart rate monitoring when:

  • You have diabetes.
  • You’re taking medicine for preterm labor.
  • Your baby isn’t growing or developing normally.

The doctor might also use a fetal heart rate monitor to make sure your baby is OK when you’re in labor or if there are other reasons to check your baby’s heart rate.
