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.
