Well, I had a touch o' the old a-fib on Wednesday, so I had to go to Northwest Hospital on Thursday and get cardioverted. Here's the strip showing the actual conversion:
One 150 Joule shock, and I was back in business. Note the irregular beats on the left, the big flat-top shock, and then the regular beats on the right. Presto!
This was my first one of these in just over three years, my longest afib-free stretch since I started having this particular problem. Can't really complain about that.
