double heart beats and abnormal EKG; EKG which the nurse said was abnormal; Feeling sick; laid down and felt like she couldn't get up; Something didn't seem right almost every day; wrist blood pressure something not going right showing abnormality-has heartbeat symbol that displays irregular heart beat that it was showing; blood pressure used to spike; scared feeling; Palpitations; Really bad heart rate, it went really high; panic attack afterwards; This is a spontaneous report from a contactable consumer (patient) via medical information team. A 71-year-old female patient received first dose of bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE, solution for injection, lot Number: EP7534), dose 1 via an unspecified route of administration, administered in upper left arm on 19Mar2021 at 11:00-11:30 (at the age of 71 years) as dose 1, single for COVID-19 immunization. The patient's medical history was none. Concomitant medications included Bentyl for the stomach. After the first dose of Pfizer Covid-19 shot on an unspecified date in Mar2021 (week later, maybe onset of 25Mar2021 or 22Mar2021, she was not sure) she was feeling sick. Also, around midday she felt really sick, laid down and felt like she couldn't get up. On an unspecified date in 2021 the patient mentioned she had palpitations, really bad heart rate, it went really high. Shot made her go into panic attacks which she had never had before. On 31Mar2021 she made an appointment, had to go into the doctor's office. The doctor was not available, so the nurse took an EKG and said it was abnormal, she could hear the double heart beats. The nurse referred her to another doctor to get an echocardiogram to look at her heart, but he didn't see any red flags. This was scary. Something didn't seem right almost every day. When she took her wrist blood pressure something was not going right with showing of abnormality-the wrist blood pressure machine has a heartbeat symbol that displays an irregular heartbeat that it was showing. Blood pressure used to spike. Nothing seemed right, it was just erratic. No one called it inflammation, but she mentioned maybe it was inflammation of the heart. No other testing was performed, and her other EKG came out normal. Patient also received her second dose of bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE, solution for injection, lot Number: EW0151), dose 2 via an unspecified route of administration on 09Apr2021 (at the age of 71 years) as dose 2, single for COVID-19 immunization and said she felt fine after taking it. Clonazepam was given as a therapeutic measure for panic attack. The panic attacks would happen randomly, and now has only occurred maybe 1 time in the last month, so panic attacks have improved. When she took clonazepam, it would go away. In the first few months it happened every 2 weeks where something would trigger the panic attacks. Atenolol was given as a therapeutic measure for blood pressure. Her blood pressure would spike and then the scared feeling she would get which has subsided significantly, it went ok. The outcome of the events was recovering except for the panic attacks which was not recovered. Patient believes these events started subsiding after her appointment with the doctor's office and saw the nurse on 31Mar2021.  Follow-up attemps are completed. No further information is expected.
