Interactive resting pulse checker

Pulse ranges are wider in infants and young children and become lower as children grow. This checker uses age-based resting references from MedlinePlus.

For a resting pulse, the person should be calm and resting. Exercise, fever, pain, anxiety, dehydration, medications, and body temperature can change the rate.
