Hi my house mate is a male, and he asked me to touch his heart the other day it was beating uncontrollably fast!! The next day when I asked him about it he said he has a family history of heart problems and didnt want to talk about it, then this morning he was shaking so bad he couldnt tie the laces on his boots.. He wont go to the dr and he just tells me to stop worrying.. Any ideas on what this is, im going out of mind with worry :?
