Somatics a sophisticated electroshock therapy unit manufacturer that has been making these machines since 1938. The technology has been steadily improving and these units have started featuring chart readouts of the sessions and also ekg deep wave read outs. This machine is capable of both. Comes with leads to both etc and ekg terminals. I have fired it up- and the unit turns on, but has not been 'tested' in the medical sense. I am sure this thing will do what it is supposed to , but AGC just loves the design and we collect medical electronics that we find interesting or historically relevant. We are sure you will find this a nice addition to your Electroshock / Medical collection.
