A pulse of 84 beats per minute is normal. This is because the normal range of pulse in a person at normal rest is 60-100 beats/min. In the case of an average young person, a pulse of 84 beats per minute does not require any intervention. However, in the case of elderly patients, or patients with coronary artery disease, angina pectoris, or hypertension, it is advisable to control the pulse rate more slowly, which will help prevent the occurrence of insufficient blood supply to the heart muscle. It can also improve the lack of blood supply to the heart muscle and can better improve other uncomfortable symptoms of the patient. The main drugs chosen to slow down the pulse are beta-blockers and non-dihydropyridine calcium channel blockers, in addition to the new If channel blocker Ivabradine and other drugs that can further improve the pulse. It is recommended that the patient’s pulse should ideally be controlled at 55-60 beats per minute, with greater benefit for older patients or those with underlying disease.
