Abstract

A mathematical model of abnormal gastric electrical activity is presented and used to investigate the accuracy of surface EGGs in the detection of gastric electrical abnormalities. The results show that current surface electrode configurations, cannot detect abnormalities that are not widespread. Substantial improvements can be obtained by using electrode arrays. Surface maps of the slow waves and the signal-to-noise ratio of the array EGG are plotted, and features representing abnormalities at the different electrode locations are identified
