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?
The general advice was to take things easy and listen to how I feel, my AFib was paroxysmal with attacks generally occurring 1 to 2 times a week, since the ablation I’ve had no instances of an irregular heartbeat but still feel that my heart rate is a little fast and don’t feel ready to move from the fast walking stage, it sounds like 6 weeks may be the correct timeframe although again based upon how I feel at the time.
