A 70-year-old female patient received bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE solution for injection), via an unspecified route of administration on 12Mar2021, 10:45 Am at a major hospital (age at vaccination was 70 years) (Batch/Lot number was not reported) as 1st dose, single for covid-19 immunization. The patient medical history and concomitant medications were not reported. On 12Mar2021 within an hour of receiving the vaccine patient was sent to the observation area, felt fine and went home when she left, she had a little heat later her skin turned a little red and had no rash. On 14Mar2021 morning around 5 o'clock she woke up, her heart was pounding as like her heart flipping out, slamming between into her shoulder blades and an increased heart rate, she did not know if she was having a heart attack. She stated her back was sore from the heart pushing too hard. She calmed down but her heart was still pounding and said that she could feel it beating hard, it is not pain, more like a soreness inside of her body pounding so hard and her body was exhausted. She went to the emergency room on 16Mar2021 and on 19Mar2021 and went to a cardiologist and had an EKG. When they did her EKG they told her that she was the 4th person to come in there with a rapid heartbeat after the vaccine. She was put on a beta blocker to slow the heartbeat and she was on a halter monitor and needs it to slow her heart rhythm. She went to an allergist because she did not know if it was an allergic reaction and she gave her a shot of Benadryl, which did not really do anything. She stated this was a really severe reaction with the first shot, most symptoms in people are in the second. She cancelled her second dose of vaccine. Her physician said that having her heartbeat this strong for a long time can damage the muscle. She stated she has no heart history in her life, and she was not sure what was going to happen. She had a nice peaceful calm heart rhythm before. She had continued to have to take medication for 6 weeks now. The patient wanted to know if her heart rate increase was permanent or if with time it would return to a more normal rate and that she could discontinue using the medication. when she was in the ER, which was twice last week, the doctors were trying to explain it to her by drawing on the chalkboard. The patient underwent lab tests and procedures which included blood test: unknown results, electrocardiogram: fast pounding heartbeat on an unspecified date. patient received treatment for she did not know if it was an allergic reaction. The outcome of the event experiencing an elevation in the heart rate/severe, fast, pounding heartbeat was not recovered and the other events was unknown.
