Like others have said, PFA is effective. I spent 10 months with paroxysmal afib, very symptomatic. I used metoprolol 37.5 mg followed 45 minutes later by flecainide. It is called pill in the pocket. It always worked within 80 minutes of taking the flecainide. There are risks to it, you can't have coronary artery disease. The last time I had to do it, 5 days before my ablation in May, my heart stopped for 6 seconds. That was interesting. I always monitored myself with my wellue so I could see when I flipped. I could always tell because my heart would stop for about 2 seconds and then my chest pain would go away. I found using diltiazem didn't work as well as the metoprolol. I couldn't tolerate metoprolol when I wasn't in afib, my heart rate would go in the 30s when I was up and about and I would find myself going down. I don't know if there are too many PFAs getting done these days or not, but I'm so glad I got mine. My heart is so much better, it feels great to be able to exercise again.
