导言在测试和评价心电波记录器、心律不齐监视仪及其他ECG仪器时,对于实验室测试和现场测试,ECG测试信号是必不可少的。目前,为了达到这一目的,使用的是磁带记录器或简单振荡型的综合器。这种简单振荡型的综合器,由于不能显示ECG波形轮廓的变异,因此,对于测试识别ECG波形态复杂心电监测仪来说,就不十分有用了。磁带记录器的缺点是:(1)假如使用8磁道注释磁带,仅有限的几种波形及其变态能 Introduction When testing and evaluating ECG recorders, arrhythmia monitors and other ECG instruments, ECG test signals are essential for laboratory and field testing. Currently, for this purpose, tape recorders or simple oscillators are used. This simple oscillator type synthesizer, because it does not show the variation of the ECG waveform profile, is not very useful for testing complex ECG monitors that identify ECG waveforms. Disadvantages of tape recorders are: (1) If 8-track annotation tapes are used, only a limited number of waveforms and their metamorphic
