ABSTRACT:
A system for electronically representing in wave form plural physiological phenomena, viewing this representation, and simultaneously obtaining a labeled permanent photographic record of the representation. While of general application, the system has particular utility in low-cost medical observance and recordation of electrocardiogram wave forms. The data from the patient is presented on the cathode ray tube of an oscilloscope. This representation is viewed via an assembly of mirrors by the observer and simultaneously by a camera. When the observer is content with the output, he activates the camera which takes a permanent picture of the wave forms displayed on the cathode ray tube. The camera shutter is synchronized with the cathode ray tube display such that the shutter is held open for one complete sweep of the electron beam.
