Description
An Electrocardiograph is a medical instrument that detects, displays, and records the electrical activity of the heart over a period of time, normally using electrodes attached to the surface of the skin. Its main use is to measure the rhythm of heart contractions and the relative strength of different parts of the heart muscle.
This is a control unit for an electrocardioscope. This part supplies the electrode voltages to the cathode-ray tube and also houses the heart rate circuit and a time-base which deflects the spot on the cardioscope screen. It would originally have been housed in a wooden box.
