A pulse of 90 to 100 beats per minute is usually normal. The pulse is produced because of the stimulation and pressure on the blood vessels caused by the contraction of the heart to eject blood. Pulse influences are generally similar to heart rate. The normal adult pulse is 60 to 100 beats/minute when quiet and awake, slower in older adults, slightly faster in women, faster in children, <3-year-olds may be above 100 beats/minute. A pulse of 90 to 100 beats/minute is usually normal. The strength of the pulse is related to cardiac output, pulse pressure, and peripheral vascular resistance. A strong pulse with a high amplitude is due to a large cardiac output, wide pulse pressure and low peripheral resistance, as seen in hyperthyroidism and aortic insufficiency. A weak pulse with low amplitude is due to a low heart rate, low pulse pressure, and high peripheral resistance, as seen in heart failure, aortic stenosis, and shock. If you have an abnormal pulse or other obvious discomfort, please consult the hospital in time to avoid delaying your condition.
