Did you see any reduction in ability post Ablation?
In general, in AF, the atria become enlarged, and this, by interfering with the speed of conduction of electrical impulses, "helps" to maintain AF. When normal sinus rhythm is restored, it takes several weeks - 6 is the figure often given - for the atria to shrink back to normal size. Before they are back to normal size, the risk of AF recurring is higher than when they have shrunk. So, for example, exercise + large atria = higher risk of recurrent AF than exercise + normal sized atria.

What did your Cardiologist say as to the timing of resuming significant exercise?
