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:

sound from EKG by Matthew M. Conroy

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.
