摘　　要：自从Alvarez在1922年首次采用体表电极描记了消化道的电活动以来,国内外学者对胃肠生物电信号都广泛地开展了研究,肯定了胃电节律与幅值同胃肠运动的相关性。近十几年来,国内也出现了不同型号的胃电仪定型产品,开始广泛应用于临床。本文将避开繁复的信号分析理论,以国产胃电仪检测记录的信号为依据。Electrogastrogram (EGG) is refered to as recording a complex electro - oscillation in this paper. It is composed of many simple electro-oscillations of different frequencies and amplitudes.Suppose that oscillation curve have n + 1 extremum points with the coordinates (t1,v1).Where t1 is time, V1 is voltage value at the time t1. Thus, there are average half period T/2 andaverage amplitude V:Two parameteres F and A are defined as complesity degree of EGG. The physilogical & pathological informations are contained in these physical quantities: period, amplitude, frequency change, amplitude change and so on.
