What does fetal heart rate ultrasound check?

Everyone knows that pregnant women need to do fetal heart monitoring during pregnancy, mainly to see whether the fetal heart is beating normally. The fetal heart beats very fast compared to pregnant women. Generally, fetal heart color Doppler ultrasound examination is done during the fourth to fifth month of pregnancy, because the fetal heart beat is basically stable during this period. So what does fetal heart color Doppler ultrasound check?

What is fetal heart rate?

As the name suggests, this is the abbreviation of fetal heartbeat, which can usually be monitored through a stethoscope during the 4th and 5th months of pregnancy. In the early and middle stages of pregnancy, the baby's heartbeat is irregular. It is sometimes fast, sometimes slow, and sometimes even stops suddenly. It is mostly in the range of 120-160 beats/minute, and sometimes exceeds this range. This is all normal. In the later stages of pregnancy, the fetal heart rate will gradually become regular. But if the fetus often behaves abnormally, you need to contact a doctor immediately for examination.

How long does it take for a fetal heartbeat to appear during pregnancy?

The baby's heart begins beating 16 days after the mother's conception, and begins to take shape around one month into the pregnancy, but it is still too weak to be tracked.

The reason why doctors recommend expectant mothers to start creating medical records and doing B-ultrasounds at the 12th week of pregnancy is because the fetal heart rate can be detected by an ultrasonic stethoscope during this period. Expectant mothers can also detect the fetal heart rate using a home fetal talker. The baby's heartbeat is like a running pony.

At 17-20 weeks of pregnancy, the doctor can monitor the baby through a stethoscope. At this time, the baby's heartbeat is very clear through the stethoscope. Their heartbeats are not as fast as those of adults. Doctors can determine whether a child's growth is abnormal based on the heartbeat.

However, some expectant mothers have thicker fat, or the baby's position in the abdomen changes. These factors will hinder the detection of related instruments. There is no need to worry too much, just work hard with the doctor and be prepared.

The beat of the fetal heart can reflect the baby's health status. Expectant mothers must carefully monitor the changes in the baby's fetal heart rate. If any abnormal situation occurs, they must go to the hospital for medical examination in time to prevent accidents.
