Atrial Fibrilation brought on by turning on right side in bed?

Almost everything that I have read from people with AFib have said is that laying on their left side brings on attacks of AFib and turning to their right side eases it, but I am having the opposite problem. If I turn to my right side, especially if my stomach is full, I will go into AFib. I have been told that when I had a chest X-ray for another problem that I had a hiatal hernia and I don’t know if this is the cause or not. Does anyone else experience Atrial Fibrillation when lying on their right side?
