The normal range of heart rate for an 80 year old is 60-80 beats per minute. However, as a person ages, he or she tends to experience a gradual slowing of the heart rate and a gradual increase in blood pressure. Therefore, if an elderly person has a fast heart rate, he or she is relatively more likely to experience symptoms of myocardial ischemia and heart failure. It is advisable for elderly patients to keep their heart rate at 55-60 beats per minute, which is most beneficial to them. If the patient’s heart rate does not reach this range, it can be improved in combination with oral related drugs, such as oral beta-blockers, representative drugs such as bisoprolol and metoprolol, which are the preferred drugs. If patients cannot take such drugs, they can retreat to non-dihydropyridine calcium channel blockers, which are more commonly used in clinical practice, such as diltiazem extended-release tablets, which also help to further slow down the heart rate.
