MOTM

This may come off as OT but bear with me...
I just had an EKG today, and forgot to take the patches off until I got
home. Naturally I became curious and tried one out with the VOM (after I
peeled it off, of course). It appears to produce voltage (.2v). Does
anyone know what these things are? The ones I have are labeled "3M Red
Dot". Maybe I'm still a little off from the anathesia, but it seems that
one could have a bit of fun switching a MOTM-700 with these babies
(using opto-isolation, please). Step a sequence with heart rate, switch
between two sequences w/ the '700 using skin resistance, ect.
Performance art, natch.
