After the primitive heart tube beat disappears, it usually does not reappear. In the early stage of pregnancy, the embryo is usually found to have primitive heart tube pulsation, the initial fetal heart, by ultrasound examination at 6 to 8 weeks of pregnancy. If primitive heart tube pulsation was found before, but the primitive heart tube pulsation is found to disappear after re-examination, it means that the fetal heart has stopped beating, and the primitive heart tube pulsation usually will not reappear. In this case, the main consideration is that the fetus may have stopped developing. You can consider going to another hospital to confirm the diagnosis. If it is clear that the primordial heartbeat has disappeared, you should follow the doctor’s advice to have an abortion as soon as possible, otherwise, it may affect the intrauterine reproductive environment of the pregnant woman. After the disappearance of the primitive heartbeat, it usually does not reappear. Pregnant women with this condition are advised to undergo a comprehensive medical examination before the next pregnancy.
