Since you have only had three episodes of paroxysmal AFIB since 2015, why would you want to take any medication at all? With episodes as infrequent as yours, I wouldn't even consider antiarrhythmics and you are miles away from needing an ablation. Unless your episodes last for many, many hours and your heart rate is dangerously high during them, I would just try to learn to live with them. (I have paroxysmal AFIB and lived with it for over 10 years) If your heart is otherwise structurally sound, the type of AFIB you have is not considered dangerous. If possible, try to recall what was happening in your life when you had these episodes. Virtually all of us with AFIB have triggers that set off an episode. For me it's stress and anxiety, so I do a lot of work to manage both of those. I would recommend you have a long talk with your cardiologist about your concerns and how YOU want to manage your AFIB. I hope that discussion will give you the peace of mind you're searching for.
