Heart palpatations can be caused by many things- low sodium, potassium, calcium, magnesium, chloride, abnormalities in the way the heart sends out signals to beat, etc. You need to get it checked out. True, low sodium can be a factor, but to get the symptoms, you need a lot of water, since dehydration from sweating would cause it to concentrate again. It's really important to not self-diagnose this sort of thing :)
