I have had afib for many years, been on many drugs, been cardio converted many times, and undergone 4 ablations to fix the problem! I have no heart plumbing issues other than the “electrical” functioning, and did the first ablation to get off meds. After 3 months I was in flutter, then 3 more ablations and no solution! So now I am on Flecainide 50 mg twice a day (was 100 2xday but it’s lowered and do fine, albeit with some palpitations now and then, but I live with those). Over the years I have been on Rhythmol, Multaq, amiodorone, and Tikosyn (that one was terrible for me) and now the Flecainide which has been great for 5 years now. If you can try low dose and it works for you (and if your heart is otherwise in good shape) you should give it a try. I do often wish I had not started the ablation route bc here I am (67 yo F) after 4 ablations still on meds! I do take 25 mg of metoprolol succinate daily too to keep heart rate down. It’s been as high as 250 beats when I need a conversion. But none since Flecainide so for now I am sold on that drug. My doctor was supposedly the best in the Orlando area but I think I was a challenge to him, and I go to someone else now, BTW.
Just hoping if you do an ablation that they can get to the issue the first time and you are one and done! I will send good thoughts your way!
