This maximum rate is based on the person's age. An estimate of a person's maximum age-related heart rate can be obtained by subtracting the person's age from 220. For example, for a 50-year-old person, the estimated maximum age-related heart rate would be calculated as 220 - 50 years = 170 beats per minute (bpm).
The resting heart rate decreases as kids get older. 1  Typical normal resting heart rate ranges are: 2  babies (birth to 3 months of age): 100â150 beats per minute. 3  kids 1â3 years old: 70â110 beats per minute. 4  kids by age 12: 55â85 beats per minute.
