Abstract

A deflection is applied to an ink jet (12) in two perpendicular directions to produce a high-speed XY recording and as in 72-18060 repetitive signals can be prevented from overlapping on the readout paper by suddenly increasing the paper speed or taking up a loop of paper, either being triggered by a time signal or by a specific part of the waveform being recorded. The basic apparatus considers waveforms from a heart with the display being in the form of a vector cardiogram. In such traces loops can be formed when the paper is at rest. The apparatus may be modified to slowly move the paper in order to find the direction that movement around the loop took place.
