Your question and one of the above answers highlights one of the numerous problems in going to a place like Mars for an extended period. While on Mars or in any lower gravity environment, those stabilizing muscles and circulatory muscles all over your body will not need to work as hard, if at all, to keep you going because the gravity is not there to challenge them. This includes your heart. Imagine not having to pump as hard to get blood where it needs to go, if you can imagine this, then you can understand that unnecessary strength will be removed in a process called atrophy, or muscle reduction. This happens not only to muscles but all support structures in your body. If the strength is not needed anymore, it will be taken away, and if you tried to come back to earth without re-acclimation, you would probably have heart problems, fractures and breaks in bones, and many other problems. Your question opens up a box of problems that, if solved, would make space travel infinitely more safe.

Don't know about my *heat* rate -- i might have a little temperature from the exercise.

The excitement of being there would raise my *heart* rate. But after a few days, resting inside a dome, my heart rate would be less than on earth. This is because the gravity on Mars is only 38% of Earth gravity.

At first your heart rate would increase. After all being on mars would be exiting. Once you adjusted and calmed down it would slow. mars is much colder than Earth and your body would try to preserve vital functions for as long as possible. In addition the heart may not pump as quickly because the gravitational pull on mars (it would not have to work as hard as it does on earth to move blood from one place to another). Occasionally, however, the heart rate would peak during your attempts to escape solar flares.

I assume you mean heart. Once you calmed down it should be.
