Panic and palpitations in pregnant women are common clinical symptoms, which are classified into physiological and pathological causes. The details are as follows: 1. Physiological causes: the pregnant women themselves are not feeling well, or their metabolism is accelerated, causing panic and palpitations, which have no effect on the fetus; 2. Pathological causes: organic heart diseases and endocrine disorders, which have certain effects on the growth and development of the fetus. If a pregnant woman is combined with severe anemia, the reduced blood oxygen will cause fetal growth retardation; if combined with hypothyroidism, it will cause fetal mental development retardation. It is recommended that pregnant women with panic attacks and palpitations go to a regular hospital in a timely manner to rule out organic diseases through systematic examination and assess whether the pregnancy needs to be terminated.
