Thanks for the replies 
The heart beating thing only happens when I'm extremely deep in trance, and stops as soon as I get up, so it probably is the heart chakra.. Guess it just takes some getting used to
I'll try using relaxation techniques before laying down trying to project, I think I was still stuck in the physical in my Solar plexus area.. I read about this in the book Astral Dynamics, wish I could recall what it said to do, but I gave the book away
