Covid vaccine side effect?

My mom got the first dose of the covid vaccine on Friday.

Since Saturday she’s been feeling miserable.

But one of the symptoms she’s having, that I can’t find online, is a slower heart rate. Her heart right now is at 32, it’s never been that low and her O2 is at 94. She’s obese, has high blood pressure and diabetes.

Can anyone out there tell me if they know of anyone that had the same side effect????

I’m a little worried and don’t know what to do or who to call.

EDIT: Thank you so much ladies for the responses. I called our urgent care and spoke to the nurse who suggested we call the ambulance. They ended up taking her to the ER and I definitely will be reporting this to VAERS!!!!

Edit 2: my mom needs a pacemaker, cause her heart has a partial block... the doctor says it’s not a known side effect of the vaccine... my mom was perfectly fine before getting this stupid vaccine and now she needs a pacemaker!!! Obviously this was from the vaccine!!
