Funny you said that about jab, everyone that has a-fib, but me , had the jab to keep their jobs, my value was bad for a long time, had know idea I was born with heart defect, all the other things that developed were from not getting blood to my body, I don’t know how to get Dr. to do scan’s on your value’s, but backing up blood in your heart and causing pressure to spit tube, should have been addressed sooner by my cardiologist .
