The relative significance of electrical spike potentials and intraluminal pressure waves as quantitative indicators of motility was studied from registrations in the human small intestine. The time interval between spike potentials and corresponding pressure waves was inversely proportional to the magnitude of the pressure waves. Amplitude and duration of pressure waves were proportional to the degree of visible activity as observed by synchronized cinefluorography. Duration of spike potentials also correlated well with visible intestinal activity, whereas amplitude of spike potentials showed a great range in variation. Correlations between all possible combinations of the four parameters (1) amplitude of spike potentials, (2) duration of spike potentials, (3) amplitude of pressure waves, and (4) duration of pressure waves were calculated on a computer for 1,000 corresponding pairs of spike potentials and pressure waves. |
