Atrial Fibrillation (AFib) Support Group
Atrial fibrillation (AF or afib) is an abnormal heart rhythm (cardiac arrhythmia) which involves the two small, upper heart chambers (the atria). Heart beats in a normal heart begin after electricity generated in the atria by the sinoatrial node spread through the heart and cause contraction of the heart muscle and pumping of blood.

Glad you are back in NSR! Be careful with those woodworking machines!!
Woodworking is also a hobby of mine. I'm constantly nicking myself one way or another and bleeding all over the place, I just try to avoid the big injuries (like cutting a finger off on the table saw!).
This yr. my PCP wants me to have the High dose Flu vaccine...cuz of my age.
I don't see a collaboration, other than excessive stress.
My problem remains anxiety, which can also precipitate tachycardia. So I'm tip-toeing back into my usual exercise regime to convince myself that I'm fine. It's for psychological reasons now more than biological, I believe.
I spent the last many months anxiety free and hope to return soon!
I have to wonder why the flu would cause us to go out of NSR? Is it more likely that we become more susceptible to dehydration and inflammation etc when we are ill? What otcs are we taking that may impact our conditions also? Best defense is to stay healthy and if we do get sick, treat naturally because meds statistically lessen the flu by 1 day only.
As to why these illnesses bring on afib--that's a good question. But they can and do.
A review of 50 studies that included more than 70,000 adults found that 100 people needed to be vaccinated to avoid one case of flu. That means the vaccine failed 99 percent who took it they received no benefit at preventing the flu."
