Pfizer vacine, bradycardia and Afib

Posted by kancha @kancha, Apr 27 12:50pm

I have Afib since 2017. Since 2018 I am on Tykosin( dofetilide) it has kept me in sinuous rhythm. Most of the time my pulse rate was in between 50 to 65 ( Fitbit shows). Three weeks after I took my second dose of Pfizer vacine for corona my heart rate has changed from 65 to 85. I am no more in bradycardia. As there has been no change in my medicines ( Eliquis 5 mg and dofetilide 0.25) , my life style, diet etc. I guess it is the side effect of Pfizer vaccine. In my case it is good as I am out of bradycardia but if I already had higher pulse rate it would have triggered it.
I will inform my cardiologist about this change but I do not know how or where to send this information so that it reaches authorities who can take action or be on alert.

Hello – Even though in your case, this doesn't seem to be an adverse reaction, it is possibly a reportable event in the Vaccine Adverse Event Reporting System (VAERS). There are 2 ways to get the information into the system – contact the site where you received the vaccine, or report directly. Here are the instructions for reporting it yourself: https://vaers.hhs.gov/reportevent.html You will need your vaccine card as you will be asked information about dates, location, vaccine lot number, etc.
The more information about reactions that is communicated, the better the company can do in tweaking and perfecting the vaccine.

Should we be worried about the Pfizer vaccine?

I don't think we should worry about any Covid vaccine at this point. Just understand that your body may react in some way – just like any other vaccine. This is normal and is evidence that your immune system is responding and building antibodies.

Anything beyond the list of typical reactions listed on the information sheet they give you should be promptly reported to the site where you received the vaccine – they provide you with a contact number. The experienced staff there will triage, and advise you of the next step, which may be "watch and wait" or take Tylenol (most common), contact your primary doctor, go to the ER or call 911 (very rare!)

When you get the injection, they will ask you to register for monitoring, and you will be contacted daily for 3 days, then periodically for several weeks to report your health and any symptoms. I STRONGLY recommend doing this – it is a great way for the CDC, FDA, and pharmaceutical companies to know about how the vaccine is being tolerated. When my daughter reported a reaction to the Moderna vaccine, a triage nurse followed up with her daily until the symptoms were gone.

I had a similar reaction to Moderna (2nd dose). I take Sotalol (80 mg 2x day plus Eliqis 5 mg 2x day). My resting heart rate averages between 57-59 with dips to low 50’s. After 2nd dose of vaccine, resting heart rate went up to 64 with daytime averages up about 10-15 bmp. It only lasted about a week, then went back to normal.

Thanks I will use the link to inform Pfizer. It will help them.

Good to know that your cardio electric system came back to normal. Mine started after three weeks and it is still continue to go up ( now 85 to96 in a week). It is sixth week after it started raising.

Have you contacted your doc? A reaction that lasts that long needs to be evaluated – and perhaps meds need to be adjusted to create a "new normal." After an inflammatory response to the flu vaccine last fall, I needed a steroid injection to "reset" my body.

Yes I informed my cardiologist. Tomorrow I will see my PCP. Thanks.
