Vývoj metodiky pro měření a vyhodnocení elektrické aktivity žaludku

Abstract

This work deals with proposal of methodology of measurement and evaluation of electrical activity of stomach to offer support of diagnosis of physiological state of stomach. Outcomes of this work are methodology of measurement consisting of defined minimized electrodes layout, measurement rules and pre-processing methods, and methodology of evaluation of measured signals describing classifiers extraction procedures and their analysis using proposed fuzzy inference system. Several experimental measurements were conducted on volunteers in order to collect testing data for analysis, design and validation of principals and procedures of both methodologies. Proposed fuzzy inference system was designed based on statistical evaluation of measured data and discussion with experts from clinical environment. Reliability of the system was validated by simulations using artificial data and by evaluation of real data while in both cases the system complied, therefore it can be used for another validation in clinical practice.
