QUALITY CONTROL OF ELECTROGASTROENTEROGRAPHY SIGNALS AND MEASUREMENT OF GASTRIC CONTRACTIONS RHYTHMICITY
Annotation
The problem of noise component of data obtained with electrophysiological study of gastrointestinal tract is considered. A method of quality data control in electrogastroenterography records based on analysis of high-frequency components of measuring signals is presented. A quantitative indicator of measuring signal quality is proposed, the indicator may be used directly during the measurements recording. A positive effect of the proposed method as applied to measurement of gastric contractions rhythmicity is demonstrated.
