The normal fetal heart rate of the fetus, what is the normal fetal heart rate

A normal fetal heart rate is a normal number of fetal heartbeats per minute.

The reference range of the normal fetal heart rate of the fetus: the normal fetal heart rate is 110 160 beats per minute; Before 20 weeks of pregnancy, the average fetal heart rate was 162 beats per minute; Pregnancy 21 at 30 weeks averages 147 minutes; Pregnancy 31 to 40 weeks gestation averages 139 minutes.

The more severe the degree of fetal heart rate abnormality, the more severe the fetal hypoxia, but not all fetal heart rate abnormalities are caused by hypoxia, and it is also seen in the changes in the fetal heart rate that affect the fetal heart rate in the pregnant woman's own condition, such as fever; Pregnant women with hyperthyroidism have a fast heart rate, and the fetus's heart rate often exceeds 160 beats; Or pregnant women taking certain drugs, such as salbutamol taken during preterm birth to protect the fetus, or atropine, can cause the heart rate of the mother and child to increase.

Hello, the normal range of fetal heart rate for the fetus is 120 to 160 beats per minute, during which time it is normal.

If the fetal heart rate is normal, about 100-160, check the physical examination on time, do fetal monitoring to measure the fetal heart rate, as long as it is normal.

A normal fetal heart rate is 120 to 160 beats per minute, and the rhythm is regular. If the fetal heart rate is less than 120 per minute or more than 160 per minute, the fetal heart rate is considered abnormal. Abnormal fetal heart rate may be caused by intrauterine hypoxia, such as the umbilical cord around the neck or other compression, and the mother may have heart disease.

Or in diseases where oxygen exchange in the lungs is obstructed, the fetal heart rate increases or slows down. If the fetal heart rate is abnormal, it is necessary to immediately go to the hospital for examination, do fetal heart rate monitoring, according to the monitoring situation, judge the condition of the fetus in the uterus, take the best measures in time, and terminate the pregnancy in advance if necessary.

We can check the growth of the fetus through prenatal examinations, including the observation of the fetal heartbeat. The fetus has a normal range of fetal heart rate, so what is the normal fetal heart rate, and what are the possible influencing factors?

The normal value of the fetal heart rate is not completely constant, but changes as the pregnancy cycle increases. Normally, the normal range of fetal heart rate is 120-160 beats per minute. Before 20 weeks of pregnancy, the average fetal heart rate is 162 beats per minute; In 21-30 weeks of pregnancy, the fetal heart rate averages 147 beats per minute; By 31-40 weeks of pregnancy, the average is 139 beats per minute.

In general, pregnant women do not use ultrasound Doppler fetal heart rate for self-monitoring before 15 weeks of pregnancy. And for pregnant women at 15 to 28 weeks of pregnancy, it is safe to measure the fetal heart rate 3 times a day for 1 minute each time. For pregnant women after 28 weeks of pregnancy, the fetus is completely differentiated, which can extend the duration and frequency of monitoring.

In addition, for high-risk pregnant women after 35 weeks of pregnancy, such as pregnant women with pregnancy hypertension and hyperthyroidism, they should be hospitalized and continue to monitor the fetal heart rate with a fetal heart rate monitor, and if necessary, continue to monitor the fetal heart rate for a long time.

Therefore, the normal fetal heart rate is very important, and it is very useful for judging some conditions of the baby, so the mother must measure the fetal heart rate from time to time to ensure that she can always understand the situation of the fetus, and she can know immediately if there is any accident.

The normal fetal heart rate is 120-160 beats, if the fetal heart rate reaches 180 points, it means that the fetal heart rate is too fast. If the fetal heart rate is too fast or too slow, you need to pay attention to whether there is a possibility of fetal hypoxia. Usually check whether the amniotic fluid is too little or contaminated, or the fetal umbilical cord is around the neck.

But don't worry too much, the baby often has a problem such as the umbilical cord around the neck in the belly, which can generally be relieved by itself. However, it is recommended that pregnant mothers carefully record fetal movements, and frequent fetal movements or fetal slowness need to seek medical attention in time.

The condition of the pregnant woman itself also affects the changes of the fetal heartbeat, such as the fever of the pregnant woman, the fetal heart rate often exceeds 160 minutes, the pregnant woman has hyperthyroidism, her own heart rate is very fast, the fetal heart rate often exceeds 160 minutes, if the pregnant woman takes certain drugs, such as salbutamol taken during premature birth to protect the fetus, or with atropine, can cause the heart rate of the mother and child to increase. A slow fetal heart rate can be caused by a lack of oxygen to the fetus, but sometimes pregnant women take certain medications, such as propranol, which act on the fetus through the placenta, causing the fetal heart rate to slow down.

What is the normal heart rate of a typical fetus? Fetal heart rate is the fetal heartbeat, and during pregnancy, you can know whether the fetus is developing normally and whether there is a lack of oxygen. This is very important for fetal development monitoring.

So, how normal is the fetal heart rate? What is the normal fetal heart rate?

The fetal heartbeat is the heartbeat of the fetus, which can be heard in the abdomen with a general stethoscope at 17-20 weeks. The fetal heart rate is 120 160 beats, sometimes it is faster, and it is not very regular, and it is much more regular at the end of pregnancy.

Fetal heart rate monitoring is only a time period, so the monitoring results are only changes in the monitored time period. At about a month of pregnancy, the baby's heart starts beating. At first it was slower, only sixty or seventy times a minute.

At this time, the heart beat is very weak, and during the ultrasound examination, the fetal heart beat can be displayed from the fluorescent screen of the ultrasound. By 8 weeks of gestation, the fetal heart rate can reach about 180 beats per minute.

After 14 weeks of gestation, the fetus's heart rate decreases to about 140 beats per minute and remains at 120,160 beats per minute. In addition to listening directly to the fetal heart rate with a stethoscope, the doctor can also use a Doppler fetal heart rate detector to measure the fetal heart sound. In the late stage of pregnancy, the fetal heart rate is too fast, too slow or irregular, which indicates that the fetus is hypoxic in utero, and it should be timely.

If the fetal heart rate lasts for more than 10 minutes, it < 110 or 160 points, which is abnormal, indicating that the fetus may have symptoms of hypoxia. The fetal heart rate is regulated by the sympathetic and parasympathetic nerves, and the monitoring graph formed by the signal tracing moment of the fetal heart rate changes can be used to understand the fetal movement and contractions, and the fetal heart rate response can be inferred to infer whether the fetus is hypoxic in the uterus.

If the fetal heart rate lasts for more than 10 minutes, < 110 points or 160 points, it means that the fetus is hypoxic in utero, and you should seek medical attention immediately.

If the expectant mother does not see a doctor in time, the frequency of beats will gradually slow down, less than 110 beats per minute, and the heart sounds will become more and more inaudible, and eventually the fetus will die.

Changes in fetal heart rate in the mother's body require daily attention from mothers. If the fetus's heart rate is too slow or too fast, this is not conducive to the development of the fetus in the mother's body, and there is even a possibility of embryonic termination. So how important is it to keep the fetal heart rate within the right range, so how much is the normal range for the fetal heart rate?

A normal fetal heartbeat of 120-160 beats per minute should sound regular and gap-free. If the fetus is moving, the fetal heart rate will increase slightly. If the fetal heartbeat is more than 160 times per minute, or less than 120 times, or the heartbeat is irregular, sometimes fast and sometimes slow, the jump stops and stops, and there is a gap in the middle.

Fetal fetal heart rate is the most important means of fetal safety, so it is necessary for every pregnant woman to record the fetal fetal heart rate. At this time, the pregnant woman must know the range of normal fetal heart rate: normal fetal heart rate is 120 160 beats per minute.

Before 20 weeks of pregnancy, the fetal heart rate averages 162 beats per minute. In pregnancy 21 to 30 weeks of pregnancy averages 147 times a minute. At 31-40 weeks of gestation, the average is 139 beats minutes.

The loudest fetal heart sounds are usually heard in the abdominal wall of the pregnant woman, above the baby's back, and the loudest heart sounds vary depending on the position of the fetal head. If the fetal heart rate is less than 120 minutes or more than 160 minutes, it means that the fetal heart rate is abnormal and needs to be further reviewed.

The normal heart rate of the fetus is between 120-160 beats, experts point out that listening to the fetal heart rate needs to be done with the help of special instruments, such as happy mommy fetal language instrument, about 12 weeks of pregnancy can be used to use its Doppler stethoscope to hear the fetal heart rate in a very quiet situation, and if you use the obstetric stethoscope until 18 weeks of pregnancy can not be heard, even in the third trimester, it is not easy to use an ordinary stethoscope to listen to the fetal heart. According to the fetal heart rate, the accuracy of distinguishing men and women is higher than that of other characteristics, which has a certain scientific basis, because men's heart rate is slower than women's, so it is generally difficult for women to control their emotions when they are angry! The general heart rate is about 140 beats in the prenatal examination more than 5 times, especially the boys below 140 points, and the girls who are about 150 beats and especially the girls who score more than 150 beats occupy the majority, and the more they reach the third trimester (after 7 and a half months), the more obvious the gender difference can be distinguished.

Why can't you take the fetal heart rate once or twice to judge the gender of men and women, because sometimes the female fetus just goes to sleep when listening to the fetal heartbeat, the fetal heart rate will be lower than her normal state, and sometimes the male fetus is moving in the mother's belly when the doctor measures the fetal heart rate, so the fetal heart rate will be higher than his normal state, even more than 145 points, so it must be the expectant mother's multiple fetal test reports to roughly determine the gender of the male and female.
