The standard heart rate range for adult patients at rest is 60-100 beats/min, so if a patient has a resting heart rate of 85 beats/min, there is no risk. But whether it is normal or not is actually relative. For example, if the patient is a senior patient or has cardiovascular disease, although a heart rate of 85 beats/min is normal, it is often recommended to control the heart rate relatively slowly to help prevent the onset of uncomfortable symptoms and slow down the progression of coronary heart disease. It is relatively ideal to try to control the heart rate to 55-60 beats/min. If necessary, patients are advised to take oral beta-blockers to slow down the heart rate. The beta-blockers commonly used in clinical practice are bisoprolol, metoprolol, etc.
