Fetal heart 162 One male and one female.
People also attach great importance to the fetal heartbeat, but the focus is on gender. It is said that if the fetal heart rate is higher than 140 times per minute, it is a boy, and below this limit, it is a girl. This statement has no scientific basis. Judging from the research results in recent years, it can only show that the heart rate of baby boys is indeed lower than that of baby girls, but it has little to do with gender discrimination.
How to detect fetal heart rate
In April of pregnancy, the position of the baby's fetal heart can be tracked, but the baby at this stage is still very small, which is difficult to monitor with a general stethoscope. It is necessary to monitor with a Doppler stethoscope. It is best to learn to listen to fetal heart under the guidance of a doctor. Generally speaking, it can be traced with a common stethoscope in the17th week of pregnancy. Usually home monitoring, mostly use the following three instruments:
1. Fetal desire
The price is moderate, using Doppler auscultation technology, some instruments can directly calculate the fetal heart rate and display it on the screen, and some are specially for expectant fathers and expectant mothers.
2. Fetal Phonograph
Compared with the former, it is more intelligent and has more functions. It can not only let expectant mothers hear the fetal heart rate, but also record it, calculate the fetal heart rate and the number of fetal movements, sort out and draw the daily data into a map, and also allow doctors to monitor it remotely. At present, it has also been developed to cooperate with mobile APP, which is very convenient.
stethoscope
It is the cheapest, but it needs a certain technical content, otherwise it is difficult to track the baby's heartbeat position, and it is easy to be disturbed by the outside world and it is difficult to hear the sound.
It is necessary to remind prospective parents that many people misunderstand the murmur of placenta and uterine artery as fetal heart sound. Placental murmur is the sound made by blood flowing through the mother's placenta. The frequency of this sound is consistent with the frequency of the mother's heart, while the uterine artery murmur sounds more like wind, not as regular as the fetal heart sound.
