A heart rate of 106 beats per minute can be observed, and metoprolol can be given to treat obvious symptoms, while the cause of the fast heart rate should be found and the primary disease should be treated. A heart rate of 106 beats per minute is considered a mild acceleration of the heart rate. Clinically, a heart rate of more than 100 beats per minute is considered tachycardia, which can be caused by physiologic reasons, such as emotional excitement, exercise, and so on. Physiological causes do not require special treatment, and most of them can return to normal after the triggers are removed. If there are obvious symptoms of tachycardia, metoprolol can be given orally to control the heart rate, which can reduce the patient’s symptoms, and diltiazem can also be taken orally. Patients with fast heart rate should pay attention to find the cause, such as routine blood tests, thyroid function tests, anemia patients, hyperthyroidism can also lead to heart failure, to treat the primary disease. Myocardial ischemia, cardiac insufficiency can also appear rapid heart rate, can be given to dilate the coronary artery drug isosorbide nitrate combined with metoprolol, furosemide to reduce the cardiac load of drug therapy. Fast heart rate of patients with obvious symptoms, should promptly go to the hospital, under the guidance of the physician to clarify the specific application, and follow the doctor’s instructions to give symptomatic treatment.
