Hulk Hogan has heart scare while undergoing check-up in preparation for back surgery

According to TMZ, some sort of irregularities showed up on Hulk Hogan's EKG when he went in for a check-up as part of preparation for another back surgery.  He followed up with a cardiologist who did more extensive tests, and it appears that as far as they can tell, his heart is fine and he should be healthy enough to get the back surgery done.  His back has been in really bad shape for a while now, with plenty of stories of how badly he's functioning when not on camera, and he's already had at least one back surgery somewhat recently.
