to quote a song - wouldn't that be wonderful..... beta blockers may help as bbxx wrote, however it is not an anti-arrhythmic. A reduced heart rate from beta blocker treatment can also promote PVC's...fine balancing act.
From what I understand it all depends on the person. Everyone respond differently. Usually if a medication is tried it is a beta blocker, but I think it will depend on the amount and type of pvcs.
