Atrial Flutter and Fibrillation - Tambocor

[steve]

52 y/o male from NY w/o underlying heart disease dx with Atrial flutter and Fib in 1994 (heart ran about 130 bpm) and placed on combination of Quinidine, Digoxin, Tiazac, Atenolol and Cuomadin which obtained control most of the time. However, the effects of the meds- very low BP (90/55) and feeling tired most of the time, forced a hospitalization to change to only Flecanide (Tambocor)150 mg BID. Was in perfect sinus rhythm from 5/98 - 8/16/99 when after a few days of running 25- 30 min (which I hadn't done in a while), while on vacation in LA, my rate increased from 55-60 bpm to around 100 bpm. My MD suggested I see a cardiologist here who confirmed I was in A-flutter at 2:1 ratio and placed me on Cuomadin and Tiazac (180 mg/day long acting)on 8/19/99, and am still taking the Flecanide.  I am still in flutter and can function, but cannot be active at all. I am upset that the Flecanide failed me after it was so good for over a year.  Can it work for me again? Why would it stop working, and could the increased exercise have affected it, or does the meds stop working from time to time? The MD here mentioned cardioversion but my doc never went that route in the past. Any ideas?
