How many weeks to hear the fetal heartbeat?

The sound of the fetal heart is one of the most exciting sounds. that the parents, especially the mother, hear it. it is better All parents should know how this basic system grows and develops in their child's body.

Since you find out that you are pregnant. One of the first milestones you are probably looking forward to. Hearing the sound of the fetal heart. This article talks about the possible time of hearing the sound of the fetal heart.

Time The beginning of the growth and development of the fetal heart

even at 4 weeks of pregnancy when the heartbeat of the fetus is still not heard. A specific blood vessel has formed in your fetus. which will soon become your child's cardiovascular system.

In the early stages, the heart is like a tube. which gets curved and changes over time and finally builds the structure of the heart and its valves. In fact, by week 5, the heart tube begins to beat on its own. Although it cannot be heard. During the first few weeks, blood vessels also form in the fetus.

sound When is the fetal heart heard for the first time?

At 6 weeks, your baby's heart is now beating 110 times per minute. It has four hollow cavities. each of which has an entrance and an exit so that blood can enter and leave each cavity. Just over the next two weeks, this number of beats per minute increases to 150 to 170 beats per minute. That's almost twice as fast as your heartbeat!

Despite this growth, you'll likely hear your baby's heartbeat for the first time around week 9 or 10. At this time it will be around 170 beats per minute and will gradually slow down from then on. Your doctor or midwife will place a handheld ultrasound device called a Doppler on your abdomen to amplify the sound.

If you reach this week of pregnancy and still can't hear it, don't worry. It probably just means that your shy baby is hiding in a corner of your womb or has his back to you, making it difficult for the Doppler to find his heartbeat.

At the next visit, your doctor will check again to make sure everything is OK, and then you can hear your baby's heartbeat.

Ultrasound and diagnosis of congenital heart defects

Sometime between 6 and 9 weeks of pregnancy, your doctor will perform your first trimester ultrasound. This will not only confirm your pregnancy and estimated due date (along with your number of babies and fetal position) but also determine if the fetus's heart is beating.

During the second trimester ultrasound, the heart is checked at 18 to 22 weeks. The doctor examines the structure of the fetal heart and can detect any congenital heart defects. Every year, about 36,000 babies (or 9 out of every 1,000 babies) are born with congenital heart defects. This is the most common type of congenital disorder at birth.

There is no medicine that can treat heart defects in utero. Some minor heart defects cannot be diagnosed until after birth. But detecting these defects during pregnancy helps doctors to decide where your child will be born.

It is usually recommended in cases of heart defects. Delivery should be done in a center that has a cardiac care department for children.
