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.

通过放置在肠道浆膜下的电极，已记录到人类胃窦和十二指肠近端的起搏电位。发现胃典型的每分钟3次搏动以一定速率（2厘米/秒）通过幽门传导至十二指肠第一部，该速率约为其在更靠近近端的胃窦中传导速率（0.5厘米/秒）的四倍。在距幽门10厘米远的十二指肠远端也能检测到每分钟3次搏动的起搏电位。
