In my life, I have had 5 AFib episodes from December to recently, so I envy your having just one per year or so. Do you have other arrhythmia or palpitations regularly? Like PVCs and very short runs of super ventricular tachycardia? I always did and lived okay with them until these horrifying long-lasting bouts of AFib. I believe my single trigger is anxiety, so I am aggressively trying to mitigate that with meditation and such, no anxiety drugs, strongly considering therapy. (Would love to hear anybody’s comments on anxiety’s role in their AFib!) I also take magnesium and eat plenty of bananas. Because of my other kinds of arrhythmia, cardiologist does not recommend pill in pocket idea like you use with diltiazim. I do hope to find a way to reduce meds to your level of frequency if possible, though. I am otherwise in very good health at 75, so cardiologist recommends I do not take a blood thinner because the risk associated with the blood thinner outweighs my risk of stroke.
