Well there normal heart beat for a child (12 years or older) is between 55 and 85 beats per minute. Let’s say 65 beats per minute. There are 60 minutes in an hour, 24 hours in a day so that’s 1440 minutes per day. So around 93600 beats a day! Younger children’s hearts beat faster so they have more, and really fit people have slower hearts so they have less.
