I had atrial fib in 2005, had a successful cardioverson done in 2006. I went back into Atrial Fib sometime this winter. I seem to become lethargic, tired, and depressed. The first time I went to the doctor he said he was sure I was fine, 3 months later I returned and told him I was not getting better, something was wrong, sure enough he listens to my heart and orders a EKG, I'm in Atril Fib once again. This time seeing a different cardiologist. So far he's taking me off Rymthol, tried me on Atentenol, did not work at all, now I'm on Diltiazem, working some what, but not good enough so he added Dogix, made me feel nausated all the time, short of breath, and like I needed my cane to walk. I'm losing patience with this doctor, every month, a new pill to try. Does it take this long (now going on 3 months) to regulate A-Fib? Am I being too impatient? Are A-Fib symptons feeling lethargic, depressed, tired? Any suggestions? I did see another specialist who said he usually treats his patience with Amiodarone, which would require being hospitalized to see how I react, after reading the information on that drug, I think I better pass, I see to be quite drug sensitive to begin with. Does treatment drag on like this. I guess most of my impatience comes from feeling so tired, and lethargic.
