Transcutaneous electrogastrography

The aim of this thesis is to introduce the physiology and pathophysiology of the gastrointestinal tract, with functional parameters and appropriate diagnostics. The thesis also deals with transcutaneous electrogastrography devices and presents a suggestion of a measurement protocol which would involve a group of volunteers in fasting and postprandial states. The theoretical part describes the function of the gastrointestinal tract, detailing the analysis of gastric myoelectric activity and gastric motility. It also outlines technical and formal aspects of the parameters, artefacts and subsequent data analysis. In the practical part, a program is designed and implemented in the Matlab computing environment for the analysis of EGG recordings. Furthermore, differences between parameters in fasting and postprandial states are evaluated
