What electrolytes are important for your heartr?

Why in the world wouldn't you want to eat? Unless you're one of those anorexics we've all been hearing about. In which case I would recommend bulimia instead, twice the taste, none of the calories. Anywho, I don't think you know what electrolytes means since its any ion dissolved in water thus allowing it to conduct electricity. Its just a fancy word power drinks use to confuse, you know, people like you.
