At the 6-7th week of pregnancy,
mothers can hear the heartbeat through ultrasound equipment.
Explore the formation and development of fetal heart
Formation
process
Do you know that, from 16th day, the embryo
has two blood vessels to form heart's vessels. Although this time the shape of
the fetal heart has not been formed yet, but it also beats due to contractile
activity, it does the function of a real heart. By the end of the first month,
the embryo is 1 cm longer, fetal heart also goes into more complete process
even though the fetus has not had five organs and limbs.
From
the 16th day, the embryo has two blood vessels that form two vessels of the
heart.
To the fifth week of the pregnancy
(counting from the time of conception, your baby is 3 weeks old), the length of
the embryo is only about 1.25 mm. The embryo has formed a lot of cells. At the
end of this 5th week, the embryo begins to have shape, the nerves run along the
length of the embryo. This part will form the baby's spine and brain in future.
The upper part of the nerves begins to straighten out and it will form the
front part of the brain. A small bead in the middle of the embryo will develop
into your child's heart.
By using the modern ultrasound equipment,
sometimes we can hear the baby's heartbeat at 6th week of pregnancy.
Development process
In the 7th week, the heart grows in fetal
body and begins to divide into two parts of the heart: left and right. The
fetal heart starts beating and completes faster when the fetus is at 11th week
of pregnancy.
Five weeks after that, that is about 12th
weeks, your baby's fetal heart is almost complete. In the 14th week of
pregnancy, fetal heart beats more clearly.
After next week, that is, at around 12
weeks, your baby's fetal heart almost complete. At the 14th week of pregnancy,
fetal heart beats more clearly.
Especially at the 16th week of pregnancy,
the fetal heart can pump blood with the amount of about 24 liters/day and this
number will continue to grow along with your baby's development. At that time,
the heart is complete in structure and can undertake its functions.
From the following weeks of pregnancy until
giving birth, the fetal heart continues to grow in size and volume. Normal
fetal heart beats between 120-160 beats/minute. However, when the baby moves,
the heart may beat at the speed of 180 beats/minute, but it is still in normal
state. According to a survey of scientists, female fetal heart will beat faster
than male fetal heart.
In
the 6-7th week of pregnancy, with modern ultrasound equipment, doctors can help
you listen to the fetal heart.
When can we hear fetal heartbeat?
In the 6-7th week of pregnancy, with modern
ultrasound equipment, doctor can help mother hear the heartbeat of the baby. At
this time, doctor will place the recorder on your belly, where the fetal heart
places. The mother will feel very happy for the first time to hear the rhythm
of the baby in body. So, do not forget to bring your husband along to the
pregnant clinic to enjoy this happy moment!
When
can we hear fetal heartbeat?
However, in many cases, you can hear the
heartbeat later at about the 8-10th week of pregnancy.
From the 20th week onwards, the fetal heart
beats very strong, you just need to use normal headphones to hear it. The
father can just roll a hard paper and put it on the mother's bally to hear the
heartbeat of baby. The loud beat proves that the baby is very healthy and
developing normally.
