Is it normal for a weak fetal heart rate in early pregnancy, how normal is a fetal heart rate at 5 w

During pregnancy, there are always a lot of surprises that arise during this long phase. Some female siblings may find that the fetal heart rate is weakened sometimes. This situation cannot be left unchecked.

What should I do if I have a weakened fetal heartbeat?

1. Generally speaking, the fetus has a weakened fetal heartbeat, which does not mean that the fetus must have the serious consequences of abortion. Therefore, female compatriots must not scare themselves, so as not to affect the health of the fetus because they are too panicked. This situation may also be due to the fact that the fetal heart rate of the fetus cannot be communicated smoothly due to the wrong way used by female compatriots in fetal heart rate monitoring.

2. If the fetus suffers from some congenital diseases and pathological fetal heart rate weakening, then the serious consequences of fetal termination are relatively common. In the third trimester, if there is such a weak fetal heartbeat, then it is usually inevitable that there will be a stoppage, because it is too late to protect the fetus.

For female compatriots who are pregnant, at any period of pregnancy, they should attend the pregnancy test on time, and carry out correct fetal heart rate monitoring under the guidance of a doctor.

In the early stage of pregnancy, some according to the position of the fetus, or other reasons such as maternal fat is too thick, the instrument can not be measured, and the fetal heart rate is weak, and a comprehensive examination can be done after 12 weeks.

As for the baby, it is a long-awaited gift for parents. After the expectant mother is pregnant, many couples are more cautious, for the arrival of the baby, in the months of waiting for the birth of the baby, the expectant fathers and mothers-to-be are also crazy to make up a lot of knowledge about pregnant women and fetuses, in fact, including how to see the fetal heart rate, in what range is normal.

Normal fetal heart rate is between 110 beats and 160 beats, with an average fetal heart rate of 162 beats minutes before 20 weeks' gestation, 147 beats at 21 and 30 weeks' gestation, and 139 beats at 31 and 40 weeks' gestation. If the fetal heart beats more than 160 times per minute, or less than 110 beats per minute, or the heartbeat is irregular, sometimes fast and sometimes slow, and the beating stops and stops, etc., it is abnormal. In most cases, fetal heart rate abnormalities represent fetal hypoxia in utero, and the more severe the fetal heart rate abnormality, the more severe the fetal hypoxia, but not all fetal heart rate abnormalities are caused by hypoxia.

In addition to the above-mentioned conditions, the condition of the pregnant woman herself also affects the changes in the fetal heartbeat, such as the pregnant woman has a fever, the fetal heart rate often exceeds 160 times, 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 use atropine, can cause the mother and child heart rate to increase. In addition, in the case of umbilical cord entanglement, the fetal heart rate will continue to increase due to the movement of the fetus, which may be aggravated and the fetal heart rate will continue to increase. If this occurs before 36 weeks, the fetus can swim freely in the womb because of its small size, and the entanglement can be transient; If it occurs after 36 weeks, this kind of entanglement can cause fetal distress and even death because the fetus is in a more fixed position.

The fetal heart rate is regulated by the sympathetic and parasympathetic nerves, and the monitoring pattern formed by the signal tracing of the instantaneous fetal heart rate changes can be used to understand the response of the fetal heart rate during fetal movements and contractions, so as to infer whether the fetus has hypoxia in the uterus. 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. For normal pregnancies, fetal heart rate monitoring should be done once a week from the 37th week of pregnancy, and if there are comorbidities or complications, it can be done from the 28th and 30th weeks of pregnancy.

Attention should be paid to whether the rhythm of the fetal heart sounds is fast and slow, etc., and it is beneficial for pregnant women to learn to count the fetal heart rate per minute. If the fetal heart rate is always lower than 110 beats or higher than 160 beats within 10 minutes, or the fetal heart rate slows down, poor responsiveness, and reduced fetal movement after the fetal heart rate is accelerated, please seek medical attention immediately for examination.
