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).
1 The resting adult heart rate is normally 60 to 100 beats per minute. 2  Athletes or people on certain medications may have a lower resting normal rate. 3  The normal heart rate for children aged 1 to 8 years is 80 to 100 beats per minute. 4  The normal heart rate for infants age 1 to 12 months is 100 to 120 beats per minute. The normal heart rate for children aged 1 to 8 years is 80 to 100 beats per minute. 2  The normal heart rate for infants age 1 to 12 months is 100 to 120 beats per minute.
