Late to the party as well and I see you have decided to have an ablation done. Good choice.
Also, don't beat yourself up. Afib does not discriminate. I was probably in the best shape of my life when afib took me down. My first ablation gave me my life back. Then last year I attained a level of fitness that resembled that of years ago. Boom afib strikes again. I've had 2 ablations this year. First with the same EP as before and a second more comprehensive with Dr Natale 2 weeks ago.
My former EP had decided that what was going on was beyond what he felt comfortable doing. When I mentioned Dr. Natale he was very supportive and offered his help in any way he could. He is actually going to be who I see for my 3 month checkup. Dr. Natale will see me at the six month point.
Best of luck to you.
