This paper introduces an electrogastrograph analysis system with a microcomputer chip 8031. The system can not only record in real time EGG signals obtained from a sensor, but also carry out frequency analysis of EGG and point out the results of analysis. 本文介绍了一种采用单片微机8031构成的胃电图示分析系统。该系统不仅能实时描记通过传感器获得的胃电信号,而且能对胃电信号进行频谱分析,打印输出分析结果。
To observe stress events 'interference in cutaneous electrogastrograph, comparing the frequence characters of forearm electrodermal and electrogastrograph in healthy subjects. 为观察应激事件对体表胃电的干扰,以健康志愿者为对象,比较前臂皮肤电和胃电的频率特征;
Result Analysing on electrogastrograph of 109 cases of children, 16 cases were normal, 93 cases were abnormal. 结果109例儿童胃电图中,16例为正常胃电图,93例为异常胃电图。
