Hello. I realize I never answered your questions. I appreciate you taking the time to send me questions. Since my post I have been to the hospital with afib episodes, and trying different drugs, all of which I could not tolerate. They tried cardio version in hospital but it did not work, but eventually went back into normal rhythm naturally. Since I also have anemia for unknown reasons ( no internal bleeding, etc.), I feel I should find out about that before I make any decisions. I feel that my poor body was subjected to too much by trying four drugs, (flecainide, Multaq, and others mentioned above) one at a time, which did not work for me. I temporarily went back on flacainide when I left hospital because at least it stops the afib but had to stop a few days ago because it made me so very ill. Now without looking much further, they are recommending an AV node ablation (because I am so small and thin and pretty much intolerant to all of the potent and powerful afib drugs) and a pacemaker which is very scary. I am sending records to Mayo for second opinion on that. I feel my poor 100 pound body has been subjected to so much abuse and poison with all of this experimentation so I must get myself a rest before I go any further. In the meantime I am off flecainide waiting nervously for an afib episode, (still on Xarelto and metoprolol) still feeling weak, fatigued, cannot function at all except sit on couch. This is not living. Six weeks ago I was working full time. Very depressed and scared.
