Abstract
A suite of conversational correlation and spectral computer programs for the analysis of electrical data from the human and canine digestive tracts is described. The data being analyzed comprise electrical signals obtained from either the inside or outside walls of the stomach and small and large bowels. The basic rhythm is a low-frequency wave of about 0.05 Hz in the stomach and 0.2 Hz in the duodenum of man, and about 0.1 Hz in the stomach and 0.3 Hz in the duodenum of dogs. The interactive analysis allows the accurate investigation of changes in phase shifts and frequency spectra caused by drug stimulation and different types of vagotomy.
