If chest tightness accompanied by rapid heartbeat occurs, the patient should actively search for the primary cause, and choose the most appropriate drugs according to the primary cause in order to treat the above clinical symptoms most effectively. For example, if chest tightness and rapid heartbeat are caused by hyperthyroidism, the patient can take drugs to control the hyperthyroidism, such as Cetrimide, etc., and can also take mesylate hydrochloride to alleviate the above symptoms. If chest tightness, shortness of breath and rapid heart rate are caused by organic heart disease, beta-blockers such as metoprolol tartrate and metoprolol succinate can be taken. You can also take nitrate drugs, such as isosorbide mononitrate, and coenzyme Q10. For traditional Chinese medicine, you can choose heart-stabilizing granules, compound danshen drip pills, Tongxinluo capsule, and ginseng pine heart capsule, all of which have the effect of improving chest tightness, shortness of breath, and rapid heart rate.
