Fetal Heartbeat In Pregnancy

Fetal Heartbeat In Pregnancy

Is your baby’s heart beating normally? This is the first question that comes to your mind when you hear your baby’s heartbeat for the first time which is most probably in the first ultrasound. The first time you hear the fetal heartbeat it could feel very strange hearing the rapid heartbeat of your baby.

The heartbeat is rapid when you are pregnant and this is much faster than the heartbeat of an adult. The normal heartbeat of the fetus will keep changing as you progress through the pregnancy.

The fetal heartbeat starts when it is 6 weeks old. You can mostly hear it when you are 8 weeks pregnant and go for an ultrasound examination. You may else hear it when a fetal Doppler test is done on your doctor visit. How early will your doctor be able to pick up the sound of the fetal heartbeat is dependent on how the baby is positioned in the uterus. The pregnant lady’s weight and also the accuracy of the due date is dependent on hearing the baby’s heartbeat.

After this, the doctor will be monitoring the heartbeat of the fetus during your regular visits.

What is fetal Doppler?

The fetal Doppler is an ultrasound that can be held in the hand and it is used to monitor the fetal heartbeat. The Doppler is first covered using an ultrasound gel and it is then moved on the pregnant woman’s belly till the heartbeat of the baby can be detected. The Doppler sends and receives the sound waves which bounce from the heart of the fetus. This makes it loud for you to be able to hear the baby’s heartbeat.

How does the heartbeat of the baby change during the course of pregnancy?

The baby’s heart will begin to beat at around 5 weeks of gestation. This time the fetal heart rate is the same as the mother’s heartbeat. After this, the fetal heart rate will increase at the rate of three beats per minute each day during the first pregnancy month.

The heartbeat is pretty accurate and this lets the doctor find out the gestational age of the fetus. There are very fewer chances of miscarriage if the pregnant woman has heard the heartbeat of the baby. But if the heartbeat of the fetus is delayed by a week or more than a week then the chances of miscarriage is high.

The baby’s heartbeat is 175 bpm when the woman enters her ninth month of pregnancy. From here on the heartbeat rate starts to decelerate to around 120 to 180 bpm. The fetal heart beta also slows in the last 10 weeks of pregnancy but this is still twice as fast as the heart rate of a normal adult who is resting.


The normal heart rate of the fetal will also vary as does the normal heart rate of an adult. This could be different when the baby is moving, sleeping or doing any other activity. If you, however, feel that the heartbeat sounds abnormal then get in touch with your doctor.
