Analysis of electrogastroenterographic signals using the computer method

Abstract

Electrogastroenterography is a field that studies the condition of the gastrointestinal tract. Electrophysiological signals contain artifacts that are not directly related to the activity of the organism, and the filtration of such artifacts is an important issue. Electrogastroenterography is a field that studies the condition of the gastrointestinal tract. This method is associated with radiography, ultrasound, endoscopy. In these methods, electrical signals are taken from the surface of the abdominal cavity. For this purpose, the issues of elimination of artifactors, processing and analysis of signals on the example of electrogastroenterograms for processing and measurement of electrophysiological signals were considered.
