Thanks for the question and coming on Just Answer. I would like to say that first of all you should not drink at least for about 12 months from the atrial fibrillation as this can trigger again. I think you should avoid drinking as this can be harmful for your life because you already got episode of atrial fibrillation due to alcohol. It is important to have detail follow up with your cardiologist and in the mean while you should not drink. If you would like any additional information or have more questions please don't hesitate to ask!Please remember to only rate my answer when you are satisfied.
