Thank you for your comments on CFS. I hope the physician from the Cleveland Clinic has now researched CFS and heart problems. This is in reference from an old discussion from 2003, so I'm not sure whether or not you are still around. If you are still here, I would be interested in those therapies you mentioned for CFS.
