I have a fairly mild case as well, compared to many. I'm really hoping to grow out of it , maybe that's wishful thinking. I have passed out three times and the dizziness goes in flares. As for cardiologists at Heart Center of the Rockies, I really like Dr. Whitsitt, but he admitted that I was past the course of "orthostatic" 101, when he couldn't find my bp upon standing. That's when I was referred to Dr. Nath (EP), he knew what he was talking about, but was only in the room with me several minutes over two appointments... Because of an insurance mix up I had to see a different EP for my third visit, Dr. Johnson. He was fantastic, very open to my opinions about meds etc... This would be my recommendation. The website for Heart Center of the Rockies is, very fittingly, www.heartcenteroftherockies.com. The website has bios of doctors etc... Fort Collins is a cool town if you do make it down this way, make a mini vacation
