If a patient with coronary artery disease triggers bradycardia, the following aspects should be noted: 1. If the patient is also accompanied by hypotension, pulmonary heart disease, chronic bronchitis and other diseases, you can not take drugs such as heartthrob. The heart has the effect of lowering blood pressure and anti-arrhythmic effect, but can reduce the lung and bronchial permeability caused by asthma attacks; 2, patients who have obvious bradycardia, also can not take beta-blockers, otherwise there will be obvious atrioventricular block; 3, patients such as long-term use of coronary heart disease drugs, can not suddenly stop the drug on their own. Therefore, for some people with coronary artery disease causing bradycardia, if the medication needs to be adjusted, they must go to a large hospital and make adjustments according to the doctor’s instructions. If the patient has an obvious angina attack, must contain drugs such as nitroglycerin or quick-acting heart pills while in the upright position.
