Howie Mandel was on the Dr Oz show a couple days ago. He talks about his OCD and some other stuff, and then they talk about his AFIB and his ablation. Dr Oz shows him a real heart and demonstrates how AFIB happens. Howie is very funny talking about what he went through, but it's all very interesting. His visit is broken up into a few short segments, but you can see them all on DoctorOz.com -- just search for Howie Mandel in the search box on the top right.
ADDED: I'm sorry, I should have gone into more detail on how to find it. His time on Dr Oz was broken up into several different segments (between commercials). You have to either watch the first three before you can get to the one where he talks about his AFIB. OR they show little thumbnails underneath the video -- click on the 4th one to go straight to the AFIB one. But all his segments are interesting, esp the one where he talks about his OCD.
Preparing for a ' discussion!'

Moving into permanent Afib?
Unfortunately the wrong video comes up, despite the right title appearing in the search box.

That worked! He is one funny guy and must have done a lot to raise awareness of stroke risk and AFib in the US. Thanks, recommended viewing, especially the story about his ablation. Hilarious.
