I do not think that Statin drugs directly cause Afib, but from my own experience - and I had been on Statins for many years before they discovered my RBBB
and an excessive amount of PACs
and PVCs - I am convinced that they are the cause of this. Why? While on Statins I had severe Rhabdomyolysis affecting basically my whole body. After a trip to the ER, because of severe pain in my kidney area, they could not find a cause for this and sent me home with an injection of Dilaudid.
