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!!!
