retnav, I am SO happy that you are going to get a cath. The more you tell us, the more worried I am.
As far as the stent goes, there are guidelines for exercise tolerance without pain or shortness of breath, to clear someone to dive after heart surgery or stenting. Search on recent posts by debersole -- he wrote something fairly recently about changes in those standards.
BTW, a normal EKG only tells us that the electrical pathways through the heart are normal. It is quite possible to have significant coronary artery disease and have a normal EKG, when pain isn't present (or sometimes when it is). An abnormal EKG can be very useful, but a normal one doesn't tell us much. I wish it did -- it would make my life a whole lot easier!
