I'm a young woman, under 100lbs and pretty short but I've always been pretty tiny. Nothing that worries me. What bothers me is that for about two or three years I've had a racing heart that often likes to 'skip beats'. Recently I noticed a very strong beat in my abdomen and right below my ribs.

I know for a fact that I have heart palpitations, but what is this new thing I've discovered?
Help... It worries me. Should I see my doctor about it?
