I've got it--first noticed when I was 53, got worse as I got older. Untreated I would have 2 or 3 episodes a month where my heart got very irregular beat, not pumping in rhythm so blood not circulating effectively. Could hardly walk up the stairs without fainting. My cardiologist specializes in electrical issues. He tested me and found my type of afib doesn't respond well to ablation. He put me on meds to slow my heart rate, lower my blood pressure, and prevent clotting that could lead to a stroke. Also made me quit alcohol and caffeine, which were triggers for my episodes. So far, it works pretty well for me. I have been on the new meds for about six months, and only had one episode. You need to find a cardiologist who is an electrocardiologist or an electrophysiologist.
