Thank you for this information. I was shocked when I learned I had AFib again; it had been 12 years since my ablation. They are going to do another ablation soon, but it will be 8 weeks before they can see me. I too am on Amiodarone, so I'll be watching what happens with that. Last time I had many of the shock treatments to stabilize my heart, but they never worked and the burns on my chest hurt. I've said no to doing that again and I agree with you that they might be harmful in the long term. I'm on so many meds, including Metoprolol which is making me ill. I'm so fed up with it all. Again, thank you for your information.
