MVP syndrome

Hi. I am not sure if this is the place to ask or not, but I am wondering about mitral valve prolapse syndrome. I have read some cardiologist acknowledge it and others deny it. Anyway, I have deal with symptoms my entire life from things they describe, but my mvp is considered mild, so I dont know if that is possible, yet the symptoms are there. Also I wanted to know if anyone else has mild mvp with periods of extreme fatigue. I dont think its related to my low bp because I can have my bp 90 over 60 and feel fine---so its perplexing when its 95 over 68 and I cant get out of my own way--literally---heavy feeling, so tired and groggy, and my brain feels slow-like i am half asleep. Anyone? B
