Hi , heres my take on this...

At the lowest level there is a common theme - timing

and propagation. You'll be able to find quite a bit out there about

wavelets (small circuits that chase their own tail round an

obstruction or meander around the atria) and focal points (static

locations in the heart that fire, sometimes repeatedly, out of time)

The propagation speed has to be such that by the time an errant

signal comes round and hits a cell it has already gone through

it's firing and recovery phases and is ready to be triggered again,

so sustaining the chaos.

ALL of us with AF have these attributes and I believe it's why we

appear to be susceptible at times when are hearts are changing rates or

at the extremes (sleeping/ adrenaline spikes and exercise can all

cause problems).

Adrenaline spikes are not unusual, stress is not unusual, sleep

is not unusual! Its our hearts reaction to these events that's

unusual.

I think the reasons behind why we all exhibit these timing and

propagation problems are many and varied and it's unlikely there

will ever be a one shoe fits all solution.

AFib is symptom, a catch all term for a whole bunch of problems.
