Dear Tracy, I think I can help you with your question. Heart rate shows a fairly close inverse correlation with body size. For example, the resting heart rate of a mouse is about 500-600 beats per minute. The heart rate of a dog or a person is between 60-80 beats per minute. The heart rate for really large animals like whales or elephants is probably around 25-30 beats per minute. Hope this helps, Terry
