It is unlikely his meds have anything to do with the PVCs. The Beta Blockers reduces their frequency but not eliminate them. However, any time a change occurs it should be checked with a re-evaluation. That may include blood tests, an EKG, Holter monitor and/or a cardiac (stress) echo if indicated. PVCs sometimes are a marker for underlying heart disease, and previous negative tests don’t exclude future problems.
You can check here whether you are at risk. If your heart function is otherwise normal, most often PVCs are completely benign. If necessary, Beta Blockers can be used to decrease the number of PVCs to a more tolerable level.
My advice: ask his doctors for a stress echocardiogram to make sure his bypasses are working and there is no evidence of recurrent heart disease.
Hope this helps,
