What is the reason for abnormal fetal heart rate?

Checking the fetal heart rate is an important method to measure the fetus. Through the detection of the fetal heart rate and some monitoring data, it can be found out whether the child is healthy. If the fetal heart rate is abnormal, it is necessary to check in time, understand the specific reasons, and conduct regular treatment. The most common reason is intrauterine hypoxia. If the fetal heart rate abnormality is more serious, it means that the child's hypoxia is also very serious.

What is the reason for abnormal fetal heart rate?

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 or hyperthyroidism, her heart rate is very fast and the fetal heart rate often exceeds 160 beats/minute. If pregnant women take certain medications, such as salbutamol, which is used to protect the fetus during premature birth, or atropine, it can cause the mother and baby's heart rate to accelerate. 1. 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 continues to be slow, it is important to check whether the fetus has congenital heart disease. In addition, after more than 40 weeks of pregnancy, the fetal heart rate may sometimes be lower than 120 beats/minute due to developmental problems of the fetal nervous system. Therefore, when there is an abnormal fetal heart rate, it is necessary to carefully analyze the situation and make correct judgments and treatments. If fetal hypoxia does exist, delivery should be carried out as soon as possible.

What is fetal heart rate monitoring?

The simplest way is to pay attention to the position of the fetal heart rate as the doctor listens to it, and then listen to it again yourself after returning home to determine the position of the fetal heart rate. Since the fetus can move at any time in the abdomen, the position of the fetal heart may also change. When the fetus is less than 5 months old, the position for listening to the fetal heart is usually below the navel, on both sides of the abdominal midline. When the fetus is 6 to 8 months old, as the fetus grows, the position of the fetal heart will move up. Since fetal movement usually involves the movement of the fetus's hands and feet, when you feel frequent fetal movements on the right side, the fetal heart rate is generally on the left side; when you feel frequent fetal movements on the left side, the fetal heart rate is generally on the right side. Head and breech presentation can also affect the location of the fetal heart. In the head position, the fetal heart rate is below the navel; in the breech position, the fetal heart rate is above the navel.
