Abstract

The aim of this study was to investigate the effect of electrical stimulation of small intestine in dogs. Five healthy dogs were selected in this study. Four pairs of bipolar recording electrodes were implanted on the serosal surface of the duodenum at an interval of 5 cm. Several pacing parameters were chosen to evaluate the effect of electrical stimulation. The optimal pacing parameters for entrainment were found as: pacing pulse amplitude was 4 mA, width was 160 ms, frequency was 10% higher than the intrinsic frequency (IF). Effects of changing pacing pulse width, frequency and amplitude were also analyzed. We found that appropriate electrical stimulation of the small intestine could entrain intestinal myoelectrical activity.
