This was actually quite painful, my arm bruised noticeably, but I had no swelling or flu symptoms. Lots of colleagues were experiencing much worse symptoms after the Pfizer booster and the AF forum was very concerned about the booster causing AF.
I have not had a reading of AF from the Kardia for years and have a very low ectopic burden. I test myself regularly and record ectopics I experience over the total monthly tests of 30 seconds per day; in October I had three, in November I had two.
My Heartbeat stayed normal on the day of jab and for a couple of days afterwards, with no ectopics
Three days afterwards, I had two dodgy readings. One said, “Sinus rhythm with Supraventricular Ectopy” which showed three three PACs and one “Normal” with one PAC and 3 missed beats. This is four ectopics averaged over 30 seconds, which is unusual.
I had no more ectopics for the next couple of days.
Six days after the jab, my heart went haywire. The first reading was classified as “Atrial Fibrillation” with three PACs and four missed beats. The second reading was also classified as AF, with six PACs and one missed beat). This gives eight ectopics per 30 seconds, but I was not convinced they were AF as there was some regularity between the PACs. Looking at the traces, there is a regularity to the irregular heartbeat. I think this is Trigeminy, not AF.
The seventh day was similar. I took three readings. The first was AF with three PACs and four missed beats. The second was also AF with two PVCs and seven PACs. The final one was “Sinus rhythm with PVCs” there were five PACs and one PVC. Seven ectopics per 30 second test.
The next day was back to reading “Normal” and with just one PVC detected. Although this is not entirely normal as I rarely have PVCs, the vast majority of ectopics I have are PACs.
I must admit that I was a little worried on the sixth day. I don’t normally feel ectopics and didn’t even on this day, until I saw he AF classification. When I went to bed, I could feel every missed beat. Looking back over last week, the symptoms seemed much worse then than they look on paper. I am glad I continue to monitor, in case I do regress back into AF, I will have some data for the cardiologist, but also I can look back and realise how minor this episode actually was.
