My AF has returned after a successful cardio version 5 years ago.It is much more symptomatic this time which has already seen me attend hospital 4 times in as many months with a 4 day stay in hospital last month as my hr was out of control. Yesterday I got a sudden sharp pain to the left of my chest (this happened twice) Today I have felt a kind of niggling feeling in that area. I feel ok and although I am aware of my heart palpatations this morning I'm ok.I don't really want to involve a doctor if these kinds of things are "normal" in AF.Does anybody have any ideas or thoughts? Thank you. Oh I think I need to add that I am on 7mg Bisoprolol, warfarin and digoxin and see the cardiologist on 11th July with a view to another cardio version.
