Free text: Heart was skipping beats on average of 10 to 12 beats per minute. This lasted about two hours. Its still skipping beats but not as frequently. I do have a history of my heart skipping beats an on occasion I get these episodes where it skips a lot but no know trigger. However I believe the vaccine most likely triggered my episode nut I cant be certain.
