Abstract: A method and apparatus for processing and displaying ECG waveforms and the like is comprised of a playback circuit to demodulate FM and digital signals for transcription on an endless paper loop in a series of straight lines or traces. A paper loop drive unit is capable of handling and advancing the endless loop continuously past one or more scribing pens which are offset in succession to produce a predetermined number of traces in parallel rows across the length of the loop with time segment markings closely correlated with the information recorded.

Abstract: An electrical interconnection is provided between a patient and physiological sensing or monitoring equipment. A permanent electrode is formed with a thin flexible housing which encases an electrical connector such as a pellet or nodule so that a portion of that connector is externally exposed on one surface. A disposable pad formed of a thin flexible base frame has a central bore and a double-faced adhesive disc on one side for attachment of the electrode surface containing the connector and concurrently retaining a conductive gel within the disposable pad for electrical communication with the electrode conductor. The adhesive on the opposite surface of the disposable pad is adapted to secure the pad to a selected area of the skin of the patient.
