My atrial fibrillation was first detected via an EKG about a decade ago and I have been in atrial fibrillation for approximately the last three years, most of it without any treatment for the condition whatsoever.

I now take furosemide (strong diuretic) for it and yet it seems to be persisting. Since I also have Obstructive Sleep Apnea I would not be too surprized at having atrial fibrillation as well.
