    Abstract

    The pacesetter potential of the gastric antrum and proximal duodenum has been recorded in man by electrodes placed under the serosal coat of the gut. The typical 3 cycle/min of the stomach was found to be conducted across the pylorus into the first part of the duodenum at a rate (2 cm/sec) about four times as fast as its conduction in the more proximal antrum (0·5 cm/sec). A 3 cycle/min pacesetter potential could be detected as far distally in the duodenum as 10 cm from the pylorus.
