Can regular prenatal checkups prevent fetal heart abnormalities?

Regular prenatal checkups can generally prevent fetal heart abnormalities to some extent, but cannot completely prevent them.

Regular prenatal examinations include various components such as blood pressure measurement, urine tests, blood tests, and ultrasound examinations, which generally can prevent fetal heart abnormalities to a certain extent. Among these, ultrasound examinations can directly observe the fetal heartbeat and promptly detect abnormalities such as fetal tachycardia, bradycardia, or irregular heartbeats. Early detection allows doctors to take timely measures, reducing the risks associated with abnormal fetal heart conditions and protecting the health of the fetus.

However, it should be noted that fetal heart abnormalities may be caused by multiple factors, including fetal hypoxia, congenital heart defects, maternal diseases, and genetic factors. These factors may not be entirely predictable or preventable through prenatal examinations. Moreover, even if prenatal test results are normal, the possibility of fetal heart abnormalities cannot be completely ruled out, as such abnormalities may occur at any stage of pregnancy.

In daily life, pregnant women are advised to consume sufficient nutrients, including proteins, vitamins, and minerals, to support fetal growth and development. They should also avoid excessive fatigue and strenuous exercise to prevent adverse effects on the fetus.
