elevated heart rate

[just1me]

I am not a physician, but from past experience, I can tell you that when you are dehydrated, your heart rate goes up. It has to do with the thickness of your blood. Staying hydrated is important; however, if you are on a fluid reduced or limited diet, that makes it hard. Hope this helps...
