experiencing shortness of breath, "fast heart rate" and "blood sugar over 200; heart skipped a beat; my heart skipped a beat, a tachycardia; experiencing shortness of breath, "fast heart rate" and "blood sugar over 200; experiencing shortness of breath, "fast heart rate" and "blood sugar over 200; feeling winded walking the 10 feet to the washer/dryer; feeling winded walking the 10 feet to the washer/dryer; This is a spontaneous report from a contactable consumer (patient). This 67-years-old male patient received BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE), dose 2 via an unspecified route of administration on 17May2021 as single dose for covid-19 immunisation.  Medical history included COPD, emphysema, diabetes, and drinking and smoking for 40 years, had Covid illness in January of 2021 and waiting 3 months before being vaccinated. The patient's concomitant medications were not reported. Historical vaccine included first dose of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE) for covid-19 immunisation and experienced a little bit like the flu and having trouble breathing. Patient had since been experiencing shortness of breath, "fast heart rate" and "blood sugar over 200" reporting " blood sugar has never been that way before". He thought that his increased heart rate could have been a symptom of his inhaler use, but read "shortness of breath" in fact sheet for the vaccine. He reported feeling winded walking the 10 feet to the washer/dryer and that's without even bending over. Patient reported he's going to lung doctor again today.  He wanted to know when normal function will return? or if the symptoms will resolve now and return in 6 months?  Patient had COVID in January, he went out he had test done for blood, he still have antibodies but they said he can still go ahead and has a shot, so he had the first shot of Pfizer and then he had the second one, well in between there he was having trouble breathing, he had got COPD and he thought it was his medicine (unspecified medication), he thought it was his inhalers (further clarification unknown hence captured as event conservatively). He was realizing today looking back that it was the medicine, honestly it was the medicine he knew that. And he had the Pfizer the second shot on last Monday on 17May2021, Monday this week and Friday he was the hospital (further not clarified) and his heart skipped a beat, a tachycardia. And he went back in to the doctor again this week and they've 'half' his medicine, he was better the medicine seems to be working but that's what happened and he went to the pharmacist, he went to the pulmonary doctor today for his breathing and he can hardly go without anything and he did not know why this all happened. What patient was upset with was saying if his health is going to return okay that the question he wanna know. Patient doctors both heart doctor and lung doctor are 'actually one' clinic, he told them he asked if this was from this and they said yes it could fairly very well and the nurse practitioner told him that she had seen cases where the heart jumped in and out of rhythm from the heart with people that taken this. Outcome of the events was unknown.  Information on the lot/batch number has been requested.
