The normal values of pediatric heart rate are based on age. From 7 days after birth to 1 year of age, the heart rate of children is 110-150 beats per minute; from 1-3 years of age, the heart rate is 90-130 beats per minute; from 3-5 years of age, the heart rate is 80-120 beats per minute; from 5-10 years of age, the heart rate is 70-110 beats per minute; and from 10 years of age and older, the heart rate is generally 60-100 beats per minute. The heart rate of children can be increased by disease states such as fever, or by emotions and after running and jumping activities. When a child is febrile, the heart rate increases by about 20 beats per minute for every 1°C increase in body temperature.
