The POLYGRAM NET ElectroGastroGraphy Application is intended to record, store, view and analyze gastric myoelectrical activity as an aid in the diagnosis of gastrointestinal motility disorders.
EGG is a non-invasive technique that permits prolonged and repeated recordings of gastric electrical activity
EGG detects abnormal myoelectrical rhythms, providing an easy way to define motor pathophysiology; it helps doctors to stratify patients and improve confidence in their therapheutic recommendations

Position of EGG electrodes
In normal humans we see an increase in overall amplitude after a meal
Increased signal power/amplitude postprandially
No increased signal in response to a solid meal.
The dominant frequency postprandially is abnormal: tachy- and/or bradygastria / dysrythmia
