I was diagnosed with atrial fibrillation that causes cardiomyopathy four years ago, when I was 15. Since that time all of my dreams have been crushed because of it, I do not want to let hiking the AT be another crushed dream. I plan on discussing my hiking plan with my cardiologist, I am not going to do this blindly. I would appreciate it if you would save your comments concerning my safety. I know the risks that I would be taking and I have deeply considered this and will only do it if I feel that I can do it safely. I guess my question is: Have you guys heard of anyone hiking the appalachian trail with a heart problem? or heart transplant? Any information that you could give me would be appreciated.
