Dynamics analysis of electrogastrography using Double-Wayland algorithm.
The electrogastrography (EGG) is an abdominal surface measurement of the electric activity of the stomach. It is great clinical importance to record and analyze multi-channel EGGs, which provide more information on the propagation and co-ordination of gastric contractions. The aim of the study is to estimate the dynamics that generate electrogastrography Double-Wayland algorithm was applied to the analysis. As a result, all the components of multi-channel EGGs can be generated from a chaos process. We found 5 or 6 independent essential components from EGGs.
