If a patient has a rapid heart rate of 120 beats per minute, the most effective way to solve the problem is to identify the cause of the rapid heart rate and administer the corresponding treatment according to the cause. There are physiological and pathological causes of rapid heart rate. For physiological factors, no special medication is needed, and the treatment requires avoiding the triggers, for example, if the patient drinks too much alcohol or strong coffee or tea, which stimulates the sympathetic nerve and causes rapid heart rate, avoiding the triggers can alleviate the problem. If it is caused by excessive nervousness, anxiety or anger, avoid excessive anxiety in the nervous system, or take a small amount of drugs such as glutamate tablets can be relieved. If the tachycardia is caused by pathological factors, such as hyperthyroidism, you can take medications for hyperthyroidism, such as Sage. If the patient’s tachycardia is caused by insufficient blood supply to the heart muscle, he can take heart stabilizing granules or beta-blockers, such as betalactam, etc., which can relieve the tachycardia.
