Profusely sweat/get sweaty quickly; Dizzy/Light-headed; Erratic blood pressure; Erratic heart beat; Almost passed out and fell on the steps; permanent heart damage; These symptoms were what caller found "disturbing"; Not feeling well; This is a spontaneous report from a contactable consumer (patient).  This 67-year-old male patient received the second dose of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, solution for injection, Lot number ER8731), via an unspecified route of administration, on 27Apr2021 (at the age of 66-year-old) at single dose for COVID-19 immunization. Historical vaccine includes the first of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, solution for injection, Lot number lot EP7533) on 06Apr2021 (at the age of 66-year-old) at single dose for COVID-19 immunisation. Relevant medical history included little bit of gastrooesophageal reflux disease (GERD) before receiving the vaccine for which the patient received a prescription, indigestion (before vaccination) and suspected COVID-19 (symptoms of the COVID but said it wasn't in his system, as reported) from Dec2019 until an unknown date. The patient is retired and used to pull the weeds and cut the grass and plat plants. No relevant concomitant medications were provided. Before vaccination, on 14Feb2021, the patient had a cardiac evaluation with a treadmill study ad well as an ultrasound to follow up after having indigestion concerns. The testing showed the following results: "everything was perfect, looked great!". About a week or two before vaccine, the patient had to go to the doctor, and they did a test to see if he had COVID or not or if he had it in the past. The results were that the patient never had COVID or antibodies or was never sick. In Dec2019 patient had symptoms of the COVID but said it wasn't in his system. In Apr2021, after second shot, the patient started to not feeling well, get sweaty quickly and dizzy and light headed. The patient began having "erratic heart beat and erratic blood pressure." The patient come inside, he had a blood pressure machine and his blood pressure was low. The caller' pulse was also low. The patient used to be able to walk about 2 miles a day. The patient tried doing two block and he felt sweaty, light headed. The last time before the patient went to the doctor he almost passed out and fell on the steps. The caller's blood pressure was 62/42 with a pulse of 107. The patient made an appointment with his doctor and said they changed the blood pressure medicines and the problem was his heart. The patient started to record hourly blood pressure readings for a week. Even when the patient laid down to go to bed his blood pressure was 180-190. When the patient would wake up and it would be maybe normal but his pulse was 110. The patient hadn't done anything strenuous. The patient went to a heart doctor and went through everything a determined to an ELISA test that it was a Coronavirus 2 and the shot had screwed up his heart. The patient has a heart monitor for 3 days and didn't know the results until next week. The patient's medicines were changed, and the result was as long as he stayed in the house and didn't do anything active his blood pressure stayed okay. But as soon as the patient went outside, he got halfway washing the car and had to stop. This is supposed to wear off in about 4 months after the last shot. Several of the heart doctor's patients have had this. The patient has read the information given to him and he saw a fast pulse was listed but doesn't see that his blood pressure will go erratic. These symptoms were what caller found "disturbing" and prompted his cardiology follow up. The patient won't know if there is any permanent heart damage until later which is what he is scared of.  The patient had not recovered from 'erratic blood pressure' and 'erratic heart beat' while the outcome of the remaining events was unknown.   Follow-up attempts are completed. No further information is expected.
