Heart at Rest. A childâs resting heart rate level depends, in large part, upon her age. For infants, a resting heart rate is expected to be between 100 and 160 beats per minute. In children who are 1 to 10 years old, this resting heart rate should be between 70 and 120 beats per minute.Adolescents and young adults between the ages of 10 and 18 should have a resting heart rate between 60 and 100 beats per minute.o determine your childâs maximum exercise heart rate, you must again consider her age. A childâs maximum exercise heart rate can be calculated by subtracting his age from 220. For example, a 10-year-oldâs maximum exercise heart rate should be 210, while the maximum exercise heart rate for a 16-year-old should be 204.
