In women, some patients will have panic attacks and palpitations during menstruation: 1. Usually, this is because the sympathetic nerve tone is increased in these patients, and endocrine disorders and imbalance of estrogen and progesterone secretion will occur in the body during menstruation. Therefore, patients will have clinical symptoms of panic and palpitations because of increased sympathetic tone and increased myocardial contraction, accelerated cardiac conduction velocity and increased oxygen consumption of the heart. 2. Patients will have imbalance of the neurohumoral endocrine system during menstruation, so they will also have insufficient blood supply to the heart due to compensation, and symptoms of panic and palpitations will occur at this time. 3. If the patient has obvious previous cardiac symptoms or plant nerve dysfunction, the symptoms will be aggravated during menstruation, and then there will be clear symptoms of panic and palpitations.
