Dave, I'm praying for you. My Dad suffered from AFib for 5 years after his triple by-pass. Lots of time he just had no energy, got winded alot. He had a third cardioversion to put him in normal rhythm about 6 weeks ago. His cardiologist went ahead and installed a pace maker also. He's been doing great. He's 72 and just finished building a 12x16 storage building for my Mom 'cause it was cheaper than buying a pre-fab. Hang in there.
