My cardiologist said there is a direct link between covid shots and cardiac autonomic neuropathy. Mine started two days after the second shot. I was given 8 years to live by the electrophysiologist. It has been over four years and it’s gotten a lot worse. The manufacturers knew about it before releasing it to the public. My cardiologist gave me the article out of the journal of cardiology. I can’t control my blood pressure it’s either too high too low the same with my heart rate between tachycardia or bradycardia. Some times I pass out.
