Patients who feel their heart beating badly are advised to take oral beta-blockers first. Relatively speaking this drug is not expensive and very effective. Representative drugs include bisoprolol, metoprolol, propranolol, etc. If the patient has a fast heartbeat and also has bronchial asthma, or hypotension, or chronic obstructive pulmonary disease, depending on the actual situation, oral diltiazem can also be combined to help further slow down the heart rate. In addition to this you can also combine with oral heart stabilizer pellets and other similar medications that can also slow down the heart rate. It is important to find out what causes the heart to beat so much. Only by finding out the cause and treating it for the primary disease can we really improve the current discomfort of the patient, and we can further check the thyroid function, blood count and serum ions to see if it is caused by hyperthyroidism or hypokalemia or anemia.
