Computer-aided analysis of gastrointestinal myoelectric activity.
This method of analysing gastrointestinal motility involves data collection for 12 h periods and calculations from electromyographic signals at 15 s intervals; results are printed for successive 20 min epochs. In addition, phases of regular spike activity are recognized during the interdigestive periods. The system has been used in a series of comparative measurements of duodenal activity before and after feeding, and in studies involving drug-induced regular spike activity.
