Recording of gastrointestinal electrical activity from surface electrodes.
The surface recording of electrical activities generated by the gastrointestinal tract is reviewed, with particular reference to surface recording of gastric electrical activity (electrogastrography or EGG). The available data on interdigestive and postprandial characteristics of the EGG signal in health and disease, including techniques of recording and signal analysis, are summarised.
