As people get older, the heart rate decreases after an initial increase from birth to infants 1-11 months.
Newborns 0 - 1 month old: 70 - 190 beats per minute
Infants 1 - 11 months old: 80 - 160 beats per minute...
Children 10 years and older, and adults: 60 - 100 beats per minute
I hope this is the answer you're looking for. If not, I'm sorry. ^^
