I don't think there would be much difference between Atenolol and Sectral in terms of side effects. Try one, and if you don't tolerate it, then try the other. PVC's can be isolated or can occur in salvos or bursts, but if your cardiologist says not to worry, then don't. Personally, I don't think that sporadic beta-blocker use helps to suppress PVC's, but you need to heed the advice of your own cardiologist. I hope you find this information useful.
