Donation to get the heart aflutterin'

For this week's visit, Charles Grossman brought us a working Sanborn Viso-Cardiette electrocardiograph (EKG) machine. This example of Model 51 (serial no. 3413) is a few iterations away from Sanborn's first portable EKG (you can see an early model here at the Sheffield Museum of Anaesthesia), and came with a power cord rather than a battery. Dr. Grossman's machine has a metal nameplate ("Made for Charles M. Grossman, M.D.") and a cloth cover to protect the wooden case. The electrocardiogram is recorded on paper--far inferior, to Dr. Grossman's mind, than the photographic paper used in an earlier machine he trained on as an intern in New Haven.

And yep, this one still works.
