I've been in A-Fib for two plus years.
My docs recommend I stay in it. The research shows one is no more likely to have a heart attack in A-Fib that in Sinus Rhythm.
The danger is the 1-2% chance of a stroke, a 1-2% higher risk than people not in A-Fib.. The docs say that if I take my coumadin and stay in A-Fib, rather than going in and out, I should be okay.
They hasten to add that something will kill me, however

, but probably not the A-Fib.
Issues-yes, shortness of breath if I walk too fast or too far or try to do too much in the way of exercise/physical work.
If I was a good candidate to get out of this, I would, but, again the docs tell me, the danger is greatest in passing between A-Fib and Sinus Rhythm when a clot could break loose and WHAMMO, hello stroke.
I rarely notice it, though once in a while I can feel the irregular beat of my heart.
I have enough other problems, medically, that this A-fib is pretty much the least of them.
I know God only programmed so many beats into my heart, but I don't know when that last number is coming up, so I spend as much time as possible making memories with my friends and family.
As I have said here before, I shoot trap every single day of the week (after Church on Sundays) and my wife shoots with me on her days off. We both won some stuff this last weekend at the Florida Fall Championships, so we are having a great time.
After all, we are all gonna end up the same way, some day. I have my affairs in order in my life and in eternity, so, whenever it comes, I am ready (though I am not pushing it).
