Back in January my wife had her right knee replaced. While in the hospital they noticed that she had a heart problem. Her heart wouldn't keep a constant rhythm. It would jump from 75-80 BPS all the way up to 200 BPS. She's been on a blood thinner and another heart med since she left. Her physical therapy went well and she's walking fine but now her other knee is starting to give her problems. Her heart hasn't gotten any better and now they want to perform a procedure called Cardio Version. They basically jump start her heart to try and get it on a consistent rhythm. I'm worried as shit about this. I know I rub a number of you the wrong way but, have any of you been through something like this? Good/Bad? Thanks for any knowledge shot my way.
