Cutaneous recording of electrogastrography reflects gastric mechanical activity. Epigastric leads are superior in recording characteristics than meso-gastric leads, in fasting state, 3.0 cpm waves dominate EGG recording in fasting state. In this study, we analyzed the EGG recording characteristic after feeding in 10 normal subjects. Though the physical changes of gastric shape and volume after feeding, EGG recording was dominated by 3.0 cpm waves. Epigastric leads are still superior in recording characteristics, amplitude of EGG waves and read-abilities, than meso-gastric leads, after feeding. Amplitude of EGG waves increased after feeding when compared to fasting state, suggesting increased mechanical activity of the stomach. We conclude that epigastric leads are suitable in recording of EGG in fasting and in fed state in normal subjects. This position could be most standard recording leads for EGG in clinical settings.
体表胃电图记录反映胃的机械活动。上腹部导联在记录特性方面优于中腹部导联，在空腹状态下，3.0次/分钟的波主导空腹状态下的胃电图记录。在本研究中，我们分析了10名正常受试者进食后的胃电图记录特征。尽管进食后胃的形状和容积发生了物理变化，但胃电图记录仍以3.0次/分钟的波为主导。进食后，上腹部导联在记录特性、胃电图波幅和可读性方面仍优于中腹部导联。与空腹状态相比，进食后胃电图波幅增加，提示胃的机械活动增强。我们得出结论，上腹部导联适用于正常受试者空腹和进食状态下的胃电图记录。这一位置可能是临床环境中胃电图最标准的记录导联。
