Hello fellow A-fibers,I have it too for last 9yrs or so,got some days I feel pretty bad and some days I feel good.I have an extra beat that I feel right now and sometimes it feels like several extra beats.Now my brother is going through some tests for his heart not beating right and he is starting at the same age I was when trouble started.Don't have any medical reason for the a-fib,no heart disease ,no valve problems ,no blockages just something electrical I think it's age and the insulation is worn off the wires and they're shorting out kinda like plug wires can do when they get old.Doc hasn't mentioned getting ablation but with the price of that with med. bills I already have for my son it would be out of the question,I'd just have go lay down and die I guess.
