Heart Rate of a person at different ages?

Heart rate is different at different ages. There are norms for the number of heartbeats per minute for different age categories. These norms apply to people in a calm state and a normal physique for their age. For children under 1 year old, this is from 120 to 140 beats per minute. Then this rate gradually decreases. Up to 5 years, the norm is about 100 strokes. Up to 10 years – from 80 to 90 strokes. From 20 to 55 is the norm of 60-88 beats. In older people from 65 to 70 years old, about 95 strokes are considered the norm.
