What is a normal heart rate for children?

The normal heart rate for children varies depending on age, according to MedicinePlus. Younger children around 2 years old should have a heart rate between 80 and 130 beats per minute. Children around 9 years old are expected to have slightly lower rates between 70 and 110 beats per minute.

If a child's heart rate at rest is high, it may indicate a problem, according to MedicinePlus. In these cases, it is recommended to take the child to visit the doctor. Common causes of an increased heart rate include infection and dehydration. A pulse that is very firm or irregular may also indicate a problem and should be checked out as soon as possible.
