Heart rate is measured by counting the number of beats per minute. Someone's normal heart rate depends on things like the person's age and whether he or she leads an active lifestyle. The resting heart rate decreases as people get older. Typical normal resting heart rate ranges are: 1  babies (birth to 3 months of age): 100â150 beats per minute. 2  kids 1â3 years old: 70â110 beats per minute. 3  kids by age 12: 55â85 beats per minute.
