When you ask a woman what her happiest moment is, most answers will be to have a baby. If you ask what the happiest moment is when you have a baby, most of the answers will be when you hear the baby's heartbeat for the first time. It was the first time that mother felt the baby's heartbeat through her son. Tick tock, like a clock, its tone was clear and its rhythm was neat. This sound is called fetal heart rate.
We can also know whether the fetus is normal or not by listening to the fetal heart rate. There is also a folk saying that the baby's gender can be determined by listening to the fetal heart rate. Generally, the heart rate of girls is higher than that of boys, so the fetal heart rate is lower than 140 beats/minute, and the fetus is a boy. But this is just a folk saying.
The fetal heart rate is regulated by the sympathetic nerve and parasympathetic nerve. The curve of the monitoring graph formed by the instantaneous fetal heart rate change can be used to understand the fetal heart rate response during fetal movement and uterine contraction, so as to speculate whether there is hypoxia in the intrauterine fetus.
In normal pregnancy, fetal heart rate monitoring is performed once a week from the 37th week of pregnancy. In case of complications, it can be performed from the 28th to the 30th week of pregnancy. Attention should be paid to whether the rhythm of fetal heart sounds is fast or slow. Normal fetal heart sounds are 120~160 times/minute. If the fetal heart sounds are more than 160 times/minute or last for 100 times/minute, it means that the fetus is suffering from intrauterine hypoxia, and it should be treated in time.
High sensitivity Doppler instruments, such as fetal speech instruments, which are commonly used, can hear the heartbeat like the sound of a horse's hoof when the fetus is 10 or 12 weeks old. However, some hospitals may use ordinary stethoscopes, so it will take 17-18 weeks to track the fetal heartbeat.
The fetal heart rate represents the vigorous development of another life. Its beating is the birth of a new life and the hope of a family. At this time, expectant mothers and fathers are most concerned about whether the baby is healthy, so the fetal heart is seldom used to judge the baby's gender. After all, health is the most important thing that needs to be paid attention to.
