I have had chest pain with my AFIB though I don't know it was the Paroxyml
type. What I learned with mine is that almost ever time I had AFIB there
was significant stomach gas along with it. I was told by my physician that
many people experienced the same thing. As my AFIB would back off, the gas
would come up and the "chest pain" would go away. One thing I
learned during those experiences was that by slugging down some apple cider
vinegar, it generally made my AFIB go away and it got rid of the gas. I
still believe that some my AFIB was associated with what I ate. I believe
that to be true for others as well.
