I would Google Atrial Fibrillation Association and find out how many similar sufferers there are around. It seems to be an area that needs more attention from the Medical Profession.
There are non Beta Blocker drugs that do a similar job and have been approved in the EU
IVABRADINE or PROCORALAN for example.
I am utterly non medical but have AF via a viral infection of the heart.
Also check Vagus Nerve as that is a serious contender for weird feelings of non well being. It starts in the Central Nervous System and affects the heart and bowel conditions.
Being a hypochondriac doesn't help!
