In my case, despite a strong healthy heart according to nuclear stress tests and echo cardiograms, I began having episodes of
atrial fibrillation nine months ago at the age of 66. At the time I was taking Advil for some minor joint pain and the A-Fib started. A cardiologist put me on a beta blocker, which seemed to be helping for several months, but then after having a couple of athletic injuries, I went back to sporadic use of NSAID's, and the A-Fib episodes returned.
