This is a demonstration of the heart rates of animals compared to a person. You can make a person/animal run by clicking start or stop running by clicking stop. The heart rates are shown at the top. You can also hear the heartbeats by clicking on the person/animal on the bottom but the heartbeat of the mouse sometimes does not work because it is very fast.
This was the source I used to find heart rates: http://www.merckvetmanual.com/mvm/appendixes/reference_guides/resting_heart_rates.html
