Will there be pregnancy symptoms if there is no fetal heartbeat?

Fetal heart rate is a characteristic of fetal development. However, if the fetal heart rate stops, it means miscarriage has occurred. If there is no fetal heart rate, it is likely that the pregnant woman has endocrine abnormalities or is affected by the environment and disease. So will there still be pregnancy reactions even if there is no fetal heartbeat?

The normal fetal heart rate is between 110 beats/minute and 160 beats/minute. If the fetal heart rate remains <110/minute or >160/minute for more than 10 minutes, it indicates that the fetal heart rate is abnormal. 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.
