I have posted something similar when I was post 1-week ablation. By now, I believe my heart is healed from my ablation. However, I am still clueless as to why I still experience irregular beats (not SVT beats) in my heart. I would get runs of what my EP told me is atrial tachycardia anywhere from few seconds to an hour. I believe those are not irritation beats. Sometimes when I lie down, it will start the AT beats (130-140bpm) for few seconds and then stops. Also, when I wake up in the morning, I would get funny beats (PACs/PVCs) and then it would turn into AT beats (130-140bpm). I will be seeing my EP very soon, but I am still very clueless as to what is going on with my heart. Is it normal to get another form of arrhythmia after an ablation? One more thing, my heart settled well into the 3rd month, then the 6th month it started this AT storm. I am also taking Metoprolol once a day, but it doesn't seem to help at all.
