DXJ－2型心电检查／监护两用仪的研制

The Development of Model DXJ-2 Electrocardiac Checking/Monitoring Instrument

介绍一种便携式电视显示心电检查／监护两用仪。仪器将心电信号变换为视频和射频信号，可在普通电视屏幕上显示双线实时滚动或冻结的心电波形以及坐标网格，并具有ＱＲＳ波检测、心律判别、自动冻结、报警和１６次记忆等功能。

This paper introduces a portable electrocardiac checking/ monitoring instrument which uses TV for display. By means of transforming electrocardiac signals into vidio and radio signals, the instrument is able to show double line real time flowing or freezing electrocardiogram with coordinate pattern on ordinary television screen.It also posseses the functions of QRS wave detection, arrhythmia discrimination, automatic freezing,alarm and 16 segments storage.
