Coronary atherosclerosis, and fast heart rate is not necessarily related. Coronary atherosclerotic heart disease, if myocardial ischemia episodes, episodes may be fast heart rate and high blood pressure. When myocardial ischemia does not attack, generally does not affect the heart rate. The heart rate is about to pay attention to whether there is a possibility of vegetative nerve dysfunction, anemia, infection, hyperthyroidism, arrhythmia, heart failure, pulmonary embolism and so on. Coronary atherosclerotic heart disease, if myocardial ischemia does not attack, the patient’s vital signs, such as blood pressure heart rate are not affected. Fast heart rate, such as sinus tachycardia, can occur in the presence of abnormal sympathetic hyperactivity in the presence of phytoneurologic dysfunction, or in the presence of anemia or elevated body temperature in the presence of infection. If there is hyperthyroidism, the patient is hypermetabolic and usually has an increased heart rate. If the patient has an arrhythmia such as atrial fibrillation, atrial tachycardia, supraventricular tachycardia, etc., it also manifests as a fast heart rate. The patient has arrhythmias because of impaired myocardial contractile function and an increased compensatory heart rate. If a pulmonary embolism occurs, the heart rate also increases because of symptoms such as hypoxia and chest pain. Coronary atherosclerotic heart disease patients with unexplained increased heart rate, it is recommended to regular hospital visits, further examination to clarify the cause of treatment.
