sound from EKG

I had to get cardioverted today (i.e., I was "shocked" at the ER to get me out of atrial fibrillation into normal "sinus" rhythm). I got a copy of the EKG strip which showed the two shocks, and I made a sound file from it:

I scanned the copy of the strip, then wrote a Processing sketch to create a Csound score from it and then created the sound file with Csound.

a bit o' the old a-fib

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.
