The second and deciding reason for ablation came after a week of a fib, I believe triggered by a reaction to a
flu shot. A couple trips to the emergency room,
and one night in ICU convinced me that "reasonable" control was not enough. I enjoy an active outdoor lifestyle and did not want another episode of my heart acting up when doing wilderness hiking, miles away from any medical care. (that happened before sotolol)
Ablation did the trick for me.
