I started having Afib within a week or so of receiving my Moderna Covid booster vaccine. I'm now on twice a day Metoporal and Eliquis. My pulse had always been in the low 50's as I've done cardiovascular exercise for most of my adult life without issue and never recall my heart rate above 140. I now find myself incapable of exercising on the elliptical machine as my heart rate often spikes above 155 and I begin feeling light headed (vertigo). My standing heart rate is now much higher and both my rate and rhythm are messed up. Three EKG's have confirmed I'm in Afib. My life has changed as strenuous activity is out of the question. I get tired just walking up steps. I'm under the care of a cardiologist and have a cardio version scheduled for December 21st. If this doesn't get my heart back to sinus rhythm I'll have no choice but to undergo next steps which involve more invasive surgery. Sure wish the FDA would have found this in Phase III human trials and warned us all this would happen.
