High heart rate generally excludes coronary heart disease caused by the person does not need to check the blood vessels of the heart. Normal heart rate is 60~100 beats/minute, and heart rate >100 beats/minute is called tachycardia. If the rapid heart rate is persistent or occurs frequently, it should be combined with the patient’s symptoms and signs and symptoms, and first improve the electrocardiogram, echocardiography and other tests, and if necessary, improve the examination of myocardial injury markers, if the above examination suggests that coronary heart disease, then it is necessary to further carry out the coronary artery CTA or coronary arteriography to assess the situation of the cardiac blood vessels. Patients with coronary artery disease usually have typical pain in the retrosternal and precordial regions; electrocardiogram shows ST-segment lowering or elevation, T-wave abnormality, etc.; echocardiogram shows segmental weakening of ventricular wall motion, etc.; and markers of myocardial injury can be elevated in myocardial infarction. If it is not coronary artery disease, we need to improve other related examinations to further find the cause of the disease (such as hyperthyroidism, anemia, infection, etc.).
