Causes of fetal heart arrest

The reason why pregnant women need to undergo regular check-ups is to be able to detect the developmental health status of the fetus in real time. Many times, there is no way to determine the development of the fetus through the naked eye and perception, and it can only be done with the help of medical technology. A situation like the cessation of fetal heart rate development is like a bolt from the blue for a pregnant family. It means that the fetus can no longer continue to develop, and in many cases, natural induction of labor is the only option.

(1) Endocrine disorders in expectant mothers

When it comes to the reason why the fetal heart stops developing, the embryo continues to develop after implanting in the uterus. This process relies on an extremely complex endocrine system in the mother's body. The three important hormones, estrogen secretion, progesterone secretion, and human chorionic gonadotropin, need to be coordinated with each other. Once any link is abnormal, it may lead to fetal heart arrest and miscarriage.

(2) Chromosomal abnormalities

Among the causes of fetal heart arrest, chromosomal abnormality is also a very common and typical cause. Chromosomal abnormalities include abnormalities in chromosome number and structure. Whether the chromosome number is aneuploid or polyploid, or the structure is abnormal or missing, it will cause embryonic heart arrest, fetal miscarriage, deformity, etc. In order to avoid adverse fetal delivery, expectant mothers need to pay attention to prenatal diagnosis.

(3) Reproductive tract infection in expectant mothers

We know that after a pregnant woman becomes pregnant, her hormone levels will change significantly, and her body resistance will also decrease during this process. If the mother is infected with pathogens, especially a reproductive tract infection, these pathogens may infect the placenta through the bloodstream, eventually destroying the placental barrier, leading to a series of serious consequences such as embryonic development cessation and fetal miscarriage. In order to avoid terrible consequences, expectant mothers must be careful during pregnancy to avoid these risks.
