My cyclist doctor had Afib. He had an ablation. A year later, he's doing hard rides in the mountains. No meds. He was a good candidate and of course had the best ablation doc in the state.
Uh . . . yes, people have died from Afib. It can cause clotting inside the atrium and bammo, things just got serious. Good primer here:
