I had an ablation in 2012, but it needed to be repaired -- I was told that due to my relatively young age, the scar healed at some place(s) so the signal was 'leaking' through it.
During the second ablation 9 weeks ago they decided to again isolate two veins in the left atrium, but also the superior vena cava in the right atrium.
Left me home without antiarrhythmics, but the next week after an episode with alternating AF and atrial flutter they put me on amiodarone, which I stopped taking a week ago (but due to its very long half-life should be still active in my body?).
In the meantime, I have begun having more and more skipped or premature beats (my doctor says of supraventricular origin). And the situation recently worsened, and now I have them almost constantly (10-30 per minute, with episodes of bigeminy, after sleep it is mixed with skipped beats -- looks like bradycardia) and have problems sleeping. They tend to diminish in number or go away after some moderate physical activity.
Do you have any clues about that? Could they somehow irritated or damaged the synoatrial node?
