CoronaVirus / Vaccines related problems

Just wondering, and thought I'd ask, is anyone else seeing an increase of older folks in the circles that they travel, say 70 plus years old developing a-fib?
Since about a year ago my wife and I are aware of  6 people at church who have been diagnosed with a-fib, seems kind of strange.
The common thread is that they all have been vaccinated and had boosters for the CoronaVirus. . .
Anyone else seeing a trend simular to this?
Just thinking out loud here!
Thanks.

 Aterial fibrillation (a-fib) defined as:
 An irregular, often rapid heart rate that commonly causes poor blood flow.The heart's upper chambers (atria) beat out of coordination
with the lower chambers (ventricles).
This condition may have no symptoms, but when symptoms do appear they include palpitations, shortness of breath, and fatigue.
Treatments include drugs, electrical shock (cardioversion), and minimally invasive surgery (ablation).

I have not noticed that

Yeah, my Dad. Before he was the epitome of great health for his age. Over the last couple of years he has gone downhill fast. Whenever I bring it up it’s always, well he’s old. He is old, but he was in great health.
