It's great to see that dofetilide is working for you and all the others. I just wanted to add that all anti-rhythmics stop working eventually and one learns to be happy for the time that it does. Both dofetilide and sotalol are notorious for causing QT prolongation — something to avoid at all costs hence the initial loading at the hospital. Unfortunately I did not pass that test years ago when they tried it. Now that I've had a number of ablations they want to try sotalol and see if that works. It's a long shot but a few days stay in the hospital is a small price to pay. A lot of drugs have scary side effects but the scariest of them all is amiodarone (or Vitamin A as they call it) It is highly toxic but also the only drug that worked for me after I had tried all the rest. And yet I took it for 6 years or so before it stopped working. I just had to have frequent monitoring of liver, thyroid and lung function. As for cost, I am astonished to hear how expensive the generic version can be for some drug plans — glad there are alternatives. Otherwise I would look for a better drug plan and switch.
I did have open heart surgery to replace 2 valves and fix a 3rd one… it was no picnic but I really didn't have a choice. I am also on metoprolol and am hoping it helps keep me in sinus since I am not taking anything else. I was fine for about 14 months after my 2nd ablation, was cardioverted, which only worked about 6 months. I am quite happy with cardioversion at 6 month intervals but my EPs feel I should give sotalol a shot so will do that next time I have an episode. Has been quite a journey.
