The normal heart rate at rest is in the range of 60-100 beats per minute. Although the normal range is 60-100 beats per minute, the heart rate of each person at different ages is affected by certain factors. First, for example, the human heart rate tends to slow down gradually with age, and the corresponding gradual slowdown is a protective effect on the human body and can prevent the occurrence of myocardial ischemia. Secondly, if there is an abnormal acceleration of the heart rhythm, consider the possibility that it is an arrhythmia. If you want to further clarify which type of arrhythmia is present, it is advisable to have an ambulatory electrocardiogram. Again, if it is sinus tachycardia, it is recommended that beta-blockers can be applied, with representative drugs such as bisoprolol and metoprolol. These drugs not only slow down the patient’s heart rate, but also help prevent the occurrence of myocardial ischemia and prevent the occurrence of left ventricular remodeling. It is recommended that elderly patients, especially those with cardiovascular disease, can ideally have their hearts at 55-60 beats per minute. Although the normal range is 60-100 beats/min, relatively speaking, patients benefit more if they can control their heart rate at 55-60 beats/min.
