The fast pulse rate regulation method, to identify the cause of the fast pulse rate. If the cause of the fast pulse is caused by the patient’s emotional tension, anxiety or poor sleep, the patient needs to be given sleep or anxiety mediation, if the patient’s fast pulse is caused by infection and fever, we can give the patient temperature control and control the infection to treat. If the patient’s rapid pulse is caused by hyperthyroidism, then we should treat the thyroid disease in addition to controlling the ventricular rate with beta-blockers. When the thyroid disease is under control, the heart rate will naturally return to the normal range. There may also be other diseases such as cardiac insufficiency. In order to be able to regulate the situation of rapid pulse rate, we need to find out the cause of the patient’s disease and treat it according to the cause in order to improve the situation of rapid pulse rate.
