Can I maybe check with you one thing however, why do you think an ablation ASAP given age?

Hi, I'm a fit 52yr old who was diagnosed with left atrial enlargement a few years back, suggested due to high cardio/endurance exercise. I now experience AF circa once every 2 or 3 weeks, always starts whilst sleeping and in the majority of cases I have reversed the next day via exercise. GP suggested beta blockers which I have refrained from taking until a follow-up with the cardiologist.

I have a resting HR in the 50s and my Afib episodes are circa 80s (according to my Garmin which may not be 100% accurate). So not sure if beta blocker would help or not, but I will certainly be asking when seeing cardiologist.
If you both don't mind me asking a further question, and it is in relation to exercise, what's the general view on frequency/intensity and associated benefits/risks. is this something I should be inclined to reign back either in part of totally (or maybe detrain) or I've also read articles suggesting ramping it back up may benefit?

Briar, given your exercise history and the fact you can convert to NSR with exercise, you very likely have a vagal (vs adrenergic trigger). A chronic intake of a beta blocker will likely make the afib more frequent as it will increase your vagal tone. That being said, if you have high rates (>100 BPM) during your episodes, a BB as rate control during the episode would make sense.
Have you detrained at all? If not, the endurance exercise may be a trigger also.
