Additional information: Caller is a 74 year-old female who received the booster dose of the Pfizer Covid-19 vaccine on 27Oct2021 and is having complaints of increased pulse rate. Caller also reports that she had complaints of vomiting and diarrhea the night of 27Oct2021 but this has resolved. Light diarrhea and vomiting that night. Caller is asking whether an increased pulse rate is normal after the Pfizer Covid-19 vaccine. Caller is asking how long will the fast heart beat last? There is a remote chance that the vaccine could cause a severe allergic reaction. A severe allergic reaction would usually occur within a few minutes to one hour after getting a dose of the vaccine. For this reason, your vaccination provider may ask you to stay at the place where you received your vaccine for monitoring after vaccination. Signs of a severe allergic reaction can include: difficulty breathing, swelling of your face and throat, a fast heartbeat, a bad rash all over your body, dizziness and weakness2, myocarditis (inflammation of the heart muscle) and pericarditis (inflammation of the lining outside the heart) have occurred in some people who have received COMIRNATY. In most of these people, symptoms began within a few days following receipt of the second dose of vaccine. The chance of having this occur is very low. You should seek medical attention right away if you have any of the following symptoms after receiving the vaccine: chest pain, shortness of breath, feelings of having a fast-beating, fluttering, or pounding heart. in general, local side effects; the ones you get on the arm where you got the shot (such as injection site redness and injection site swelling) were mostly mild-to-moderate in severity and resolved within 1 to 2 days. Side effects that you may experience throughout the rest of your body; (systemic side effects) including fever and chills were observed with the first 1 to 2 days after vaccination and resolved shortly thereafter. Swollen lymph nodes (lymphadenopathy), which generally resolved within 10 days, is likely to have resulted from a robust vaccine-elicited immune response. Caller states she had the shot yesterday around 11: 00a.m. and last night she had vomiting and diarrhea but she noticed her pulse has been very high all day; heart rate is running 95-110bpm and it is usually in the 50s (From: 28Oct2021 to ongoing).

Caller states she has an watch and her heart rate is running 95-110bpm and it is usually in the 50s. Caller states she didn't know what to do or if that was normal or how long it would last?
