Thanks to you all for responding but I am still in the dark with all this. in my simple way of thinking I imagined once your heart was put back into rhythm then all good - isn't that what Flecainde or similar tabs supposed to do? Whereas the beta blockers just slow down the rate but the heart rate can still be irregular. So if your take tabs like Flecainide which supposed to make u regular (like a pacemaker) then that must mean the AF Is still having a party in the background and many people seem to do okay with Flecainide so...,? It never worked for me though.
Sorry to appear so dumb but it's a hard one to get my head around. Patx
