一、导言胃电信号可通过附在腹部皮肤上的电极来进行测量。记录体表胃电信号通常称之为胃电图(EGG)。自从1922年首次测量胃电信号以来。由于它对患者和测试者无损伤,大量研究工作都花在体表EGG的测量上,但同其它电生理测量相比,如心电图(ECG)与脑电图(EEG),这种方法的实用性进展很慢。其中最重要的一个原因是体表EGG包含着许多噪声。用来改善EGG的质量或从EGG中提取相关信息的信号处理技术、包括带通滤
First, the introduction of gastric electrical signals can be attached to the electrodes on the skin of the abdomen to be measured. The body surface electrical signals are usually recorded as Electrogastrogram (EGG). Since the first measurement of gastric signal in 1922. Because of its harmlessness to patients and testers, a great deal of research is spent on body surface EGG measurements, but compared to other electrophysiological measurements such as electrocardiogram (ECG) and electroencephalography (EEG), the utility of this approach Sex is slow. One of the most important is that the body surface EGG contains a lot of noise. Signal processing techniques used to improve the quality of EGG or to extract relevant information from EGG, including bandpass filtration
