Wow did not realize so many on the board had this. I had SVT and had the ablation, best thing I ever did. But now I have atrial fib. I was meds free for about 3 years before the atrial fib came about. I take Tambacore (sp) twice a day and it stays under control for the most part. WHen I had the SVT it took awhile to find a medication that worked for me. In the end I was on Rythmol and that worked the best. When I got atrial fib. they put me back on that but when I asked if there was something I could take that would not make me so tired he switched me to tambacore.
