Is it normal for the fetal heart rate to exceed 160?

If a pregnant woman goes to the hospital for a check-up and the doctor tells her that the fetal heart rate exceeds 160, she should not be afraid or nervous at this time. She should listen to the doctor's advice. Pregnant women's emotions are prone to be unstable during pregnancy, especially when there is some bad news, and they are prone to become emotionally excited. Some emotional changes in pregnant women or some fever and other phenomena can easily cause the fetal heart rate to exceed 160. At this time, you should understand the specific reasons. Let's take a look at this aspect.

Is it normal for the fetal heart rate to be over 160?

During fetal heart monitoring, if an abnormality is found in the fetal heart graph, it is often used to indicate fetal heart abnormality. 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 will often exceed 160 beats/minute. If the pregnant woman takes certain medications, such as salbutamol taken during premature delivery to preserve the fetus, or atropine, it can cause the mother and child's heart rate to accelerate. In addition, in the case of umbilical cord entanglement, the entanglement may sometimes be aggravated due to fetal movement, and the fetal heart rate may continue to accelerate. If this happens before 36 weeks, the fetus is small and can move freely in the uterus, so the entanglement may be transient. If it happens after 36 weeks, the fetus is in a relatively fixed position and the entanglement may cause fetal distress or even death.

Generally speaking, a tachycardia can occur when the fetus is stimulated or lacks oxygen. You should reduce stimulation to your lower abdomen and uterus. Also, go to the hospital for oxygen therapy to prevent fetal hypoxia.

If the fetal heart rate is too fast, the expectant mother should pay attention to rest and fetal heart monitoring. If the fetal heart rate is always too fast, the mother should be alert to the possibility of chronic intrauterine hypoxia, which requires consideration of appropriate oxygen inhalation and hospitalization for observation.

Is the fetal heart rate of 170 dangerous?

Prenatal checkups usually involve the baby's fetal heartbeat. Therefore, many expectant mothers want to know the relevant knowledge about fetal heartbeat. So, do you know what the normal fetal heartbeat is? Now, I will share with you some relevant information about fetal heartbeat.

In a normal pregnancy, fetal heart rate monitoring should be performed once a week starting from the 37th week of pregnancy. If there are comorbidities or complications, it can be performed from the 28th to 30th week of pregnancy. The normal fetal heart rate is 120-160 beats/minute. If broken down into each week, the average fetal heart rate is 162 beats/minute before 20 weeks of pregnancy, 147 beats/minute during 21-30 weeks of pregnancy, and 139 beats/minute during 31-40 weeks of pregnancy. Attention should be paid to whether the rhythm of the fetal heart rate is fast or slow.

However, if the fetus is in a good mood, it will play in the mother's belly. At this time, the fetal heart rate will change, generally speeding up by about 20 times. It should be noted that if the heart rate is higher than 160 times per minute or lower than 110 times per minute, it means that the fetal heart rate is abnormal and you need to go to the hospital for examination in time.
