A 64-years-old female patient received first dose of BNT162B2 (BNT162B2) via an unspecified route of administration on 07Apr2021 (Batch/Lot number was not reported) as SINGLE DOSE for covid-19 immunization . Medical history included hypertension and benign heart murmur both from unknown date and unknown if ongoing. The patient's concomitant medications were not reported.  The patient experienced atrial fibrillation, swelling and aching at the injection site, lymphadenopathy, palpitations/racing, pounding, and rapid heart beat, heart beat stayed around the upper 90s all day and reached until 102 or 103, I was very uncomfortable, all two night I didn't sleep, tight chest, tightness over my chest but not any pain (chest discomfort) (non-serious) all on Apr2021.  consumer said that after receiving the 1st dose of the Pfizer-BioNTech Covid-19 Vaccine, she experienced swelling and aching at the injection site and lymphadenopathy. But she said, she is more concerned about the palpitations she had along with a racing, pounding, and rapid heart beat which came along with a rhythm. She said that her heart beat stayed around the upper 90s all day and reached until 102 or 103. Then on Thursday night, this still continued with some irregularities. Then, a day and a half after, she said she had to take beta blockers and aspirin to treat the symptoms, and noted that she calmed down after that. She also mentioned that she has a history of hypertension and benign heart murmur. I had a palpitation. My heart was pounding. All that evening I was very uncomfortable. All two night I didn't sleep. I took my pulse beat from then and every half an hour it went up to 102 and normally my pulse is not 102, it stays in nineties and I have some atrial fibrillation and I have never been diagnosed with atrial fibrillation. I have irregularities of rhythm and it didn't go away until I took (incomplete sentence) I didn't took anything until my appointment and I took a 'Ibuprofen' (Further not clarified) and a Baby Aspirin (treatment) later the next night because I want to see how I will react without medication and I got very uncomfortable and kind of tight chest, tightness over my chest but not any pain and I started taking deep breath, it was hard to do because my pulse was really high. Now I am calm down but I want to know when you get these kind of reactions that is considered a severe allergic reaction or not, according to the sheet that I am looking at I didn't know, the very first few minute because I left just you know but I have to go for my second appointment, so I will choose to sit next time, not just stand and go right after I finished, It was almost two hours after that, my pulse get raised. I have no problems with the flu shot. I do not know what was in (COVID Vaccine) it because you never have these reaction with any other shot, so now should I be concerned, would it cause damage to my heart because my pulse beat was raising and all that because nobody had made a note of this or put answers on this sheet, so that is my concern. I do not want to report, I just want my question to be answered, if I am having the side effects and is this something I should be concerned about. Why it was not included, I looked it up and this is not the normal side effects. It really doesn't matter to me. I got the vaccine and I got the side effects. All I am concerned about is a heartbeat, a rhythm I am having for 2 and half days, I want to know is this something rare and it is not unusual and it will get better, should I just go ahead and get the second one or should I not get the second one in case I got the worst side effects. That was just the whole purpose of my call."
