In 2000, I was diagnosed as borderline mitral valve prolapse with no regurgitation. In 2001, I started having the symptoms that caused my primary care physician to finally diagnose me with CFIDS after about 18 months of tests. I had another echo of the heart in December of 2002 and it now shows very mild regurgitation of the mitral and aortic valves. Could this be a result of the CFIDS? I only ask because I've read that mvp is the cause of some palpitations but that some people with cfids will have palpitations regardless of mvp...Any thoughts? Renee'
