Here is an article showing normal heart rates for children. A three-year-old can have a heart rate from 80 to 120. If his heart rate were persistently over 110, even at rest, you might want to consider a visit to his pediatrician for an evaluation.

Maximum heart rate is 220 per minute your age, so your son could have a heart rate when he is very active over 200 beats per minute. Commonly, a 3-year-old would have a heart rate of 160-180 when active and around 70-90 when asleep.
