(a) Operating room cardioscope, which is a heavy cylindrical instrument on a cylindrical pole set into a rubber-covered square fiberglass base with four wheels, at each underside corner; the base has two foot-pedals for raising and lowering the cardioscope; the front of the machine has a glass screen with two dials inside which read beats per minute and seconds; to the right f the screen is a leads dial in minivolts, which led to a recorder; to the left of the screen is another dial which controls leads to the patient; the top of the machine has a panel with 7 knobs; these knobs control sensitivity, meter zero, intensity, vertical sweep, focus and alarm; there is an electric cord coming off the machine on the right side which would have led to the recorder; there are two electric cords coming off the left side; one would have been plugged into an electrical outlet and the other would have been attached to (b) leads to the patient; these leads consist of a black electric cord, one end of which attaches to the cord on the machine and the other which separates off into 5 leads: red (RA), black (LA), green (RL), white (LL), and brown (P); all of the leads except (P) have ends which would have been put into the patient (via needles) for monitoring purposes; instrument also comes with (c) a plastic cord with a metal coupling at the end.

Storage Room W1
The cardioscope arrived very dirty and dusty; the cream paint has several chips; none of the exposed metal shows any corrosion; the rubber matting on the base has small missing sections at the corners; the electric cord is uncracked; the dials at the right and left both had pressure-sensitive tape residue, as does the leads attachment at the machine cord; the end of lead (P) is missing

This 1950's electrocardiograph is a very rare and early model and one of the first to be used in the operating room; prior to mechanized means of monitoring the patient, the pulse was taken manually; this machine was used to monitor the patient's heart rate and rhythm; it had no paper trace or direct readout; this machine featured a screen in case of sparks, as the gases employed (ether and cyclopropane) were flammable and explosive; the leads dial on the right would have led to a record calibrator
