Fetal heart rate in the early stages of fetal development
In early pregnancy, the fetal heart is the first organ to develop and begin to beat. Starting from the third week of pregnancy, the embryo begins to form a heart tube. Around the fourth week of pregnancy, this heart tube will differentiate into tissues such as the cardiac chamber, aorta, and veins. In the 6th week of pregnancy, the four parts of the fetal heart begin to form and begin to beat regularly. At this time, the fetal heartbeat can be heard through medical examination. Because the fetal heart rate is still relatively weak, with an average number of beats per minute between 100 and 120, a fetal heart rate meter is required to accurately detect it.
Fetal development at this time is the most fragile. Pregnant mothers need to pay attention to a balanced diet and avoid being exposed to greater pressure and collision to ensure the normal development and growth of the fetus.
Fetal heart rate in the second trimester
The second trimester refers to the 4th to 6th month of pregnancy. During this period, the number of fetal heartbeats will gradually decrease, but will also increase to 140 to 160 beats per minute. At this time, the doctor will recommend that the pregnant mother undergo a prenatal check-up every month to ensure the health of the fetus.
At this time, pregnant mothers should rest more, avoid strenuous exercise and sitting for long periods of time, and pay attention to maintaining emotional stability so that the fetus can grow in a warm and calm environment.
Fetal heart rate of late fetus
The third trimester refers to the 7th to 9th month of pregnancy. At this time, the number of fetal heart beats will decrease slightly, but it will still remain at about 120 to 140 beats per minute. At this time, the size of the pregnant mother will gradually increase, and she needs to pay more attention to the balance of diet and exercise, and prepare for the arrival of the fetus.
Summary
The fetal heart rate is an important indicator of fetal health. The gradually increasing number of beats and the increasing sense of rhythm are important signs of fetal growth. Pregnant mothers need to pay attention to balanced nutrition and avoid external pressure and collision at different stages of pregnancy to ensure the health of the fetus. Every pregnant mother should have regular prenatal check-ups as recommended by her doctor to ensure the healthy and safe growth of her fetus.
