[Theoretical and experimental rationale of the duration of a stimulating impulse for endogenous electrostimulators of the gastrointestinal system].
The paper presents data obtained from processing experimental findings of the electric conductivity of the actual media of the human gastrointestinal tract (GIT) as pH and temperature functions. Based on these data and experimentally derived values of electrode capacities of self-contained GIT electrostimulators in the real digestive tract, the authors calculated the values of stimulating pulse discharges. It was concluded that the discharge accumulated in the electrode containers is quite sufficient for stimulation of intestinal smooth muscle cells by using the purely capacity component of a stimulating pulse, It was shown that in this case the stimulating pulse was to be 0.8-1.2 msec.
