fetal heart rate

Fetal heart movement is a routine means of checking whether the fetal development is normal. Fetal movement is the first objective sign of fetal life. It can be measured from 6 to 8 weeks of gestation, but it is generally the first time pregnant women can feel fetal movement for the first time in four and a half months of pregnancy. The fetal heart is the heartbeat of the fetus. Generally, the fetal heart can be heard in the abdomen with a general stethoscope in 17-20 weeks. Basic Information Specialist classification: maternity check check classification: ultrasound Applicable gender: whether women are fasting: not fasting Tips: Actively cooperate with the doctor's work. Normal value The normal fetal heart is regular and powerful, like a clock ticking, 120-160 beats / min. Normally, the fetal movement is not less than 3 to 5 times in 1 hour, and the number of fetal movements in 12 hours is 30 to 40 times or more. Normal fetal movement indicates that the placenta function is good, the oxygen delivered to the fetus is sufficient, and the fetus grows well in the uterus and is very happy to move. Clinical significance Abnormal result Abnormal fetal heart rate in most cases means that the fetus has hypoxia in the uterus. The more severe the abnormal fetal heart rate, the more severe the fetal hypoxia is, but not all fetal heart abnormalities are caused by hypoxia. In addition, the pregnant woman's own situation also affects fetal heart rate changes, such as pregnant women with fever, fetal heart rate often exceeds 160 beats / min, pregnant women have hyperthyroidism, her own heart rate is very fast, the fetal heart rate often exceeds 160 beats / min If pregnant women take certain drugs, such as salbutamol taken during preterm birth, or use atopine, it can cause heart rate in mothers and children to accelerate. Slow fetal heart rate may be caused by fetal hypoxia, but sometimes pregnant women take certain drugs, such as propranolol, the drug acts on the fetus through the placenta, causing the fetal heart rate to slow down. When the fetal heart rate continues to be slow, pay attention to check the possibility of congenital heart disease in the fetus. In addition, after more than 40 weeks of pregnancy, the fetal heart may sometimes be less than 120 times due to the development of the fetal nervous system. Points, therefore, in the case of fetal heart abnormalities, it is necessary to carefully analyze the situation and make correct judgments and treatments. If there is indeed fetal hypoxia, early delivery should be made. If the fetal movement is less than 20 times in 12 hours, it is abnormal. Less than 10 times indicates that the fetus is at risk and there is hypoxia in the uterus. If the fetal movement exceeds the normal number of times in a period of time, the fetal movement is frequent, or no intermittent movement, it is also the performance of intrauterine hypoxia. The number of fetal movements is significantly reduced until it stops, which is a sign that the fetus is severely suffocated in the uterus. Abnormal fetal movement is due to pathological conditions and dysfunction, such as tight umbilical cord around the neck, placental dysfunction, or abnormal use of pregnant women and external stimuli, resulting in fetal hypoxia in the uterus. When the life of the fetus is threatened, the fetus has abnormal fetal movement, not only in the number of times, but also in nature, such as strong, continuous push-and-twist fetal movement or kicking, or even weak fetal movement. These are all ominous signs. Abnormal fetal movement should be promptly treated. Pregnant women in the population who need to be examined and those who need to have a fetal development check. High results may be diseases: fetal distress, expired birth, uterine contraction fatigue considerations Taboo before the examination: poor rest, improper diet, excessive fatigue. Requirements for inspection: Actively cooperate with the doctor's work. Or check it yourself in the right way. Inspection process Buying a fetal heart stethoscope, it is easy to learn and master the method of listening to fetal heart rate and fetal heart rate under the guidance of an obstetrician. Although the expectant mother can't hear the fetal heartbeat, she must cooperate closely with her husband to take the best position to help her husband listen to the fetal heart sound and make a record. Note that the fetal heart is most clearly heard on the abdominal wall of the pregnant woman near the back of the tire. Pregnant women can also feel the fetal movement, so pregnant women should regularly place the palm of the hand on the most protruding part of the abdomen. If necessary, measure the fetal movement once in the morning, in the middle and the evening. Each time, the number of fetal movements will be 3 times. The sum of the fetal movements multiplied by 8 is the number of fetal movements. You can also go to the hospital for inspection and test with B-ultrasound. Not suitable for the crowd People who have poor rest, improper diet, and excessive fatigue. Adverse reactions and risks No complications.
