本文介绍了以皮肤表面电极无创伤性记录胃电图和用快速富里埃变换技术进行频谱分析的方法。临床应用结果表明,该系统能实时地对胃电图的频率和幅值进行分析和结果打印。 胃电图是一种无创伤性检测胃的功能状态的客观生物电指标。近年来国内外学者对胃电图的研究相当活跃,有不少研究者对胃电的检测和计算机分析处理做了报道[1—6]。自1980年以来,作者对常见胃病患者的胃电检测方法和用计算机分析处理进行了如下探索。
This article describes a noninvasive method of recording gastroduodenal electrodes on the surface of the skin using the fast Fourier transform technique for spectral analysis. The results of clinical application show that the system can analyze the frequency and amplitude of EGG in real time and print the result. Electrogastrogram is a noninvasive objective bioelectricity indicator for detecting the functional status of the stomach. In recent years, domestic and foreign scholars on the electrogastrogram quite active research, many researchers on the detection of gastric electrical and computer analysis and treatment reported [1-6]. Since 1980, the authors have explored the method of gastric electrogastrostasis in patients with common gastric diseases and the computer analysis of the treatment as follows.
