Abstract
An electrogastrograph measures an electric signal derived from the stomach's action. The signal is decomposed into its frequency components by means of a plurality of band pass filters, and stored in a storage medium. A method for analyzing data obtained by the electrogastrograph comprises the steps of: decomposing the signal into its frequency components by means of the band pass filters; and, evaluating the stomach in its action on the basis of variations in amplitude of said frequency components.
