The Toprol I'm on is a brand name for metoprolol. I assume the Multaq you're on is an anti-arrythmilc like Rythmol which I'm on?
I was just Dx'd in September 2010 so I've got a lot to learn and am just feeling my way as well.
Are you taking coumadin (warfarin) too? I was put on that too to hopefully prevent blood clots.
My computer says I need to upgrade my brain to be compatible with its new software.
