What is the heartbeat pulse for a 12 year old boy?
When resting, the average adult heart beats at about 70 bpm
(males) and 75 bpm (females); however, this rate varies among
people and can be significantly lower in endurance athletes. The
infant/neonatal rate of heartbeat is around 130-150 bpm, the
children's heart beat is 100-130 bpm, the older child's about
90-110 bpm, and the adult's about 60-100 bpm .
