I have paroxysmal lone afib, but it’s very episodic, I’ve only had two proper episodes this year, but my Apple Watch measures that I have AF 2-10% of the time (variable).
Doesn’t really impact my cycling, not that I do hundreds of miles.
Last episode actually started while cycling, HR at 180bpm on Watch but not out of breath, but felt odd and light headed! Took a beta blocker to lower HR but episode lasted around 12 hours including while sleeping.
Saw an electrophysiologist via Bupa who suggested an ablation. Given my general lack of symptoms and all the risks he reeled off, I declined!
Alcohol seems to be a trigger too for me
