The frequency of the pulse is affected by age and gender. A normal adult pulse is 60-100 beats per minute, while an elderly person’s pulse is slower, at 60-80 beats per minute. Pulse mainly refers to the arterial pulse, which is the palpable arterial beat on the surface of the body. Pulse can be affected by emotions, exercise, etc. Exercise and emotional excitement can make the pulse faster, while rest and sleep can make the pulse slower, generally 55-60 beats per minute. When the elderly are in a state of disease, the pulse can also increase or decrease, such as sinus tachycardia, sinus bradycardia, atrial tachycardia, atrial fibrillation, ventricular pre-systole and so on. When the pulse rate increases or decreases for a long time, it is necessary to consult a doctor to find out the cause and standardize the treatment under the doctor’s guidance.
