Maybe this is a dumb question, but is there any chance that a beta blocker (metoprolol ER, the generic form
of toprol XL
) could actually increase the frequency of PACs? I was put on toprol
almost a year ago after an episode of a-fib. After taking it for several weeks, I began to have PACs more and more often. My cardiologist kept increasing the dose to reduce the PACs, but every time they just kept increasing. Now I am having extended periods every day where every 3rd or 4th beat is a PAC.
