I read a response to a post today that said their AF runs in a 3 week cycle, this at a time were I am thinking the same. I have not been in AF or Afl since my ablation in Feb 2019 but do suffer periodically from ectopics and short runs of Palpitations (or AT or MAT) - I must add that neither are particularly bad but they do remind me the all is still not as it should be. My ectopics tend to happen at rest so I believe its because my HR goes too low (around 55) and allows them to happen, the palpitation happen when I have been exerting for a period of time or under stress (I once had them for around 20 seconds in a dentist chair before root canal treatment and once for around a minute during exertion). Thankfully they go away, normally after around 10 seconds. I think I become more susceptible periodically and I am currently keeping an account to see if in fact they are cyclonic.
Whilst I believe there are many triggers I would be interested to know if anyone else has noticed such a cyclonic trend to their condition where triggers are more effective at setting the condition off than at other times. Of course it could all just be a coincidence but!!!

I can't say that my afib runs in cycles. For me since a successful CV I've had two episodes - both happened when I was traveling with little sleep (defo a 'trigger' for me).

I suggest keeping a written record of everytime this happens. Maybe you'll find a connection and can discuss this with your cardio.
Hi Shcldavies my P-AF episodes certainly seem to have have their own inbuilt clock these days and although some episodes appear to have have been prompted by getting stressed/overtired, most don't have a discernible trigger but follow a set pattern.
The pattern since last December has been a symptomatic episode every 10-12 days lasting 8-10 hours.
I asked an EP if this frequency and severity was damaging my heart and he said that was unlikely which was reassuring and it seems to be born out by a recent ECHO which is similar to one I had three years ago .
It is almost as though there is a build up of 'something' that gets released then I am ok for the next few days . I think it is very strange.
Since August I have had 2 occasions where I had 2 episodes in 3 days every 10 days, I hope this isn't a new pattern I find it exhausting and am desperately trying to be prescribed Flecainide to see if it helps.
I think there is a lot still to be learnt about AF .
It always happens at rest with me ,normally in bed when heart rate goes slow 40 or so. Triggers are tiredness,fatigue and too many ‘sherbets ‘ but a couple of pints can be beneficial may be because it increases my heart rate.

AF triggered by sleep apnea
Trigger (Not only fools and horses) 
Atorvastatin triggering AF?
AFIB being triggered by food
Exertion triggering flutter condition - ablation, or no
