Prior to my successful ablation 18 months ago, I had a reaction to a
flu shot from which I developed flu like symptoms eight hours following the innoculation. This included flu like symptoms, chest pains, shortness of breath, a-fib, and two trips to the emergency room in three days. Heart attack was ruled out. I believe the flu shot reaction triggered these episodes, but the doctors I have talked to seem unsure that this could have caused the problem.
