A heartbeat of 75 and a heart rate of 75 beats/minute is not normally needed for a normal person to take Betaloc (metoprolol tartrate or metoprolol succinate), and is needed for patients with coronary artery disease. The heart rate of a normal person is 60-100 beats/min, so for a normal person, a heart rate of 75 beats/min is normal and does not require metoprolol tartrate or metoprolol succinate. In patients with coronary artery disease, the heart rate is required to be 55-60 beats/minute at rest and 50-60 beats/minute when conditions permit. So when the heart rate is 75 beats/min, it is still necessary to continue to take metoprolol tartrate or metoprolol succinate to reduce the incidence of myocardial ischemia by lowering the ventricular rate and decreasing oxygen consumption. The need to take metoprolol tartrate or metoprolol succinate needs to be decided based on the condition of the patient, in addition to the exclusion of contraindications to its use, such as symptomatic bradycardia or hypotension, and third-degree atrioventricular block. It is not possible to stop and add the drug on its own, as prescribed.
