ABSTRACT:
An improved electrocardiography system displays and records electrocardiograph (ECG) signals provided on multiple pickup leads attached to a patient. The system has the capability of selectively displaying standard preprogrammed lead configurations or lead groups, and provides the operator with the additional capability of programming selected leads from various groups to form a "monitor group". Selected ECG signals are routed to a four-channel oscilloscope and a three-channel strip-chart recorder, the system providing the operator with a "freeze" capability such that a signal appearing on one of the oscilloscope channels may be displayed in a stationary state on the fourth oscilloscope channel, and subsequently printed out on the strip chart recorder. The system further provides an "auto lead" capability for fully automated successive recording of test data from leads in successively accessed conventional lead groups, and further provides an "auto cycle" mode of operation for fully automated repetitive recording of test data from selected leads for operator-designated recording times and at operator-designated time intervals.
