If an elderly person has a rapid heart rate, oral beta-blockers can be recommended first, and the representative drugs are propranolol, bisoprolol, metoprolol, etc. Any one of these drugs can be chosen. Relatively speaking, patients are advised to choose long-acting agents, which will not only have higher compliance, but also control the heart rate more smoothly. For those who cannot take these drugs, they can also take non-dihydropyridine calcium channel blockers, such as verapamil and diltiazem. While slowing down the heart rate, patients are advised to further identify what causes the patient’s fast heart rate, and only when the cause is clear can the heart rate be better controlled smoothly. For the elderly, it is recommended that it is best to control the heart rate at 55-60 beats/min, which will be more beneficial and less prone to heart failure or angina symptoms. Patients are advised to have an ambulatory electrocardiogram, and should also have another check of thyroid function, serum ions, blood count, and cardiac ultrasound.
