The main aim of this thesis was to investigate whether electrogastrography (EGG), the recording of gastric myoelectrical activity by means of electrodes attached to the abdominal skin, can improve our understanding of gastric myoelectrical activity in disease. The accuracy and reliability of EGG was studied by comparing cutaneous recordings with serosal recordings in a patient after laparotomy, and by performing repeat studies in healthy individuals. The fundamental frequency in the electrogastrogram in man was shown to be of gastric origin and equal to the repetition frequency of the gastric electrical control activity (ECA). The gastric ECA frequency can be measured reliable by EGG. The reliability of measurements of the postprandial amplitude increase of the gastric frequency by EGG (an indicator of gastric motor activity) can be improved by prolonging the fasting recording period but this does not seem to be necessary for clinical applications.
