Too much pressure is number one, but also when people see their heartbeat it is usually because they have too much air in their lungs and their heartbeat is bouncing off their lungs... that whole half a breathe thing. Or holding their breathe. I suppose you can get it from too much cheek pressure, but grip is more often than not the issue. if you're feeling it off the ground, its air in the lungs.
