You may need to try a few, Toprol did not work for
me pvc's broke through, I am on Atenolol and it works better for
me, I would definetily get a EP consult, they will not usually ablate PVC's. It's worth going an discussing your options. I would definetly try changing beta blockers, I would not be able to get out of bed taking 400mg of a beta blocker per day.
