Panic refers to the uncomfortable feeling of conscious heartbeat. Patients who suffer from panic do not necessarily have high blood pressure. There are many causes of heartburn, both physiological and pathological. Physiological causes can be induced by triggers, such as strenuous exercise, exertion, mental tension, emotional excitement, insomnia, heavy smoking, drinking strong tea and coffee, and the use of certain drugs such as atropine and ephedrine. Pathological causes can be seen in heart failure, coronary atherosclerotic heart disease, myocarditis, cardiomyopathy, rheumatic heart disease, congenital heart disease, pulmonary heart disease, and cardiovascular diseases such as arrhythmia. Other systemic diseases, such as anemia and hyperthyroidism, can also present symptoms of panic. In addition, patients with autonomic dysfunction, such as cardiac neurosis and menopausal syndrome, are also prone to symptoms of panic.
