Electrogastrogram
An electrogastrogram (EGG) is a computer generated graphic produced by electrogastrography, which detects, analyzes and records the myoelectrical signal generated by the movement of the smooth muscle of the stomach, intestines and other smooth muscle containing organs. An electrogastroenterogram or electroviscerogram (or gastroenterogram) is a similar display of the recording of myoelectrical activity of gastrointestinal or other organs which are able to generate myoelectrical activity.
