I was on propafenone and then flecainide for about a year after developing paroxysmal AFib about 3 years ago. I decided to go right to ablation before the meds failed. Unfortunately my ablation failed and I was back on flecainide for about 9 months and my AFib became more persistent. Another ablation was not an option due to complications from my first one. Two cardiologists recommended dofetilide (Tikosyn). I was very nervous, actually terrified, but decided to do the 3 day hospital stay and give it a try. It got me right out of Afib and has been very successful for a year now. No AFib for 9 months and now only very brief episodes less than 15 min about once every three weeks). When I got home from the hospital on dofetilide I was still very anxious for a few weeks but the anxiety went away and I am very pleased with how it’s going. I wish I had tried dofetilide before the ablation. That’s just my experience. I wish you luck with your decision!
