During pregnancy, doctors will definitely listen to fetal heart rate during prenatal check ups. As long as there is fetal heart rate, it indicates that the fetus is alive. If there is no fetal heart rate, a detailed examination is required. The absence of fetal heart rate indicates that the baby's development has stopped and the chances of fetal survival are low. What is the reason why a baby doesn't have a fetal heart?
If there is no fetal heart rate that can be detected through Doppler or ultrasound examination, and there is no fetal heartbeat, that is, if the fetus stops beating, there may be missed miscarriage due to various reasons, as follows:
1. Maternal factors: The mother may stop the fetus due to some diseases, such as hypertension or diabetes, which may easily lead to no fetal heart rate;
2. Causes of fetal appendages: Factors such as placenta, umbilical cord, or amniotic fluid, such as placental abruption or neck entanglement, can cause excessive or insufficient amniotic fluid, which can affect the normal development of the fetus;
3. Fetal self reasons: There may be congenital genetic chromosome problems. In mid pregnancy, fetal development may be affected or breast milk may be affected, leading to fetal arrest. In late pregnancy, fetal appendages are more common.
Without fetal heart rate, pregnant women may experience symptoms such as disappearance of early pregnancy symptoms and vaginal bleeding in the early stages of pregnancy. In the middle and late stages of pregnancy, there may be a phenomenon of fetal movement disappearing. If the fetal heart has not formed by 8 weeks of pregnancy, the embryo generally has stopped developing, and the early pregnancy symptoms of the pregnant woman are gradually disappearing, and the breasts are no longer swollen. Embryos that have stopped developing can cause vaginal bleeding, abdominal pain, and miscarriage in pregnant women. If there is no fetal movement in the middle and late stages of pregnancy, there will be no fetal heart rate after further examination, and there will be abnormal fetal movement before the fetal heart rate disappears.
