I have had an increase in BOTH the numbers and duration of A-fib events since having received the Moderna vaccine. Today is the 10th day of being in Afib since the second shot. (started one day after inoculation). Am scheduled for a Cardioversion in two days assuming I am still in Afib. Will also schedule an ablation in late Dec or early January--- SO regardless of what the medical people have told me--- I definitely believe there is a connection Prior to the vaccine I had one Afib event per year and each lasted less than a full day)-- Oh and I did have a very mild case of Covid in November 2020
