What is the fetal heart rate of a male baby?

Pregnant women will feel the heartbeat of the fetus in their belly in the second trimester. Generally speaking, the heartbeat of the fetus will be around 110 times. If it exceeds too much, it means that the fetal heart rate is abnormal. At this time, you must go to the hospital for further examination. But as long as it does not exceed 160 times, it is within the normal range, so it is not a case of fetal tachycardia.

What is the normal fetal heart rate for a male baby?

The fetal heart rate is the heartbeat of the fetus, which reflects the status of the fetus in the uterus. When the fetus is deprived of oxygen for various reasons, the fetal heart rate will change very sensitively. The normal fetal heart rate is 110 to 160 beats per minute. The normal fetal heart rate changes all the time with the different intrauterine environments. Changes in the fetal heart rate are a manifestation of the normal regulatory function of the central nervous system and a manifestation of the fetus being in good condition in the uterus. If the fetal heart rate is >160 beats/min and lasts for more than 10 minutes, it is called bradycardia or tachycardia.

The application of fetal heart monitors has become quite popular. During fetal heart monitoring, if an abnormality is found in the fetal heart graph, it is often used to indicate fetal heart abnormalities. In most cases, abnormal fetal heart rate means that the fetus is suffering from hypoxia in the uterus. The more severe the abnormal fetal heart rate, the more severe the fetal hypoxia. However, not all abnormal fetal heart rate is caused by hypoxia. In addition to the above situations, the condition of the pregnant woman herself also affects the changes in the fetal heart rate. For example, if the pregnant woman has a fever, the fetal heart rate will often exceed 160 beats/minute. If the pregnant woman has hyperthyroidism, her own heart rate is very fast, and the fetal heart rate often exceeds 160 beats/minute. If the pregnant woman takes certain medications, such as salbutamol taken during premature delivery, or atropine, it can cause the mother and child's heart rate to accelerate.

A slow fetal heart rate may be caused by fetal hypoxia, but sometimes pregnant women take certain medications, such as propranolol, which act on the fetus through the placenta and cause the fetal heart rate to slow down. When the fetal heart rate is persistently slow, it is important to check whether the fetus has congenital heart disease. In addition, after 40 weeks of pregnancy, due to developmental problems with the fetal nervous system, the fetal heart rate may sometimes be lower than 120 beats/minute. Therefore, when there is an abnormal fetal heart rate, it is necessary to carefully analyze the situation, make correct judgments and deal with it. If fetal hypoxia is indeed present, delivery should be carried out as soon as possible.

The more commonly used high-sensitivity Doppler instrument can hear the heartbeat like the sound of horse hooves when the fetus is 10 or 12 weeks old. However, some hospitals may use a regular stethoscope, in which case the fetal heartbeat cannot be tracked until 17-18 weeks. There is also a situation where, in the early stages of pregnancy, due to the position of the fetus or other interfering factors, such as excessive maternal fat, the fetal heartbeat cannot be heard even with extremely sophisticated instruments.
