If the fetus has atrioventricular (AV) block, if it is first degree and the symptoms are mild, it is usually possible to have it; however, if it is second degree and above, and the fetus has severe structural abnormalities or shows significant slowing of the heart rate, it is usually not possible to have it. If the fetus has first-degree AV block and has no obvious symptoms, the pregnancy can continue. However, if the fetus has second- or third-degree AV block and the fetus is associated with severe structural cardiac abnormalities or shows marked slowing of the heart rate, termination of the pregnancy is usually recommended. This is because the slow heart rate of the fetus may result in critical conditions such as shock and the child may not survive after birth. If a pregnant woman finds that her fetus has atrioventricular (AV) block during her labor and delivery examination, it is recommended that she seek medical attention in a timely manner. Under the guidance of her doctor, she should complete the relevant examinations to determine the cause of the condition and treat it appropriately.
