Electrogastrography (EGG) is a non-invasive method for the measurement of gastric myoelectrical activity. It was first discovered in 1921 and popularized in 1990s. EGG is attractive because it is non-invasive. However, due to its non-invasive nature, there have also been controversies regarding validity and applications of EGG. The aim of this review is to discuss the methodologies, validation and applications of EGG. Pros and cons of EGG will also be discussed in detail. First, the gastric slow wave and its correlation with gastric motility are presented. The association between gastric dysrhythmia and impaired gastric motility is reviewed. Secondly the method for recording the electrogastrogram is presented in detail and pitfalls in the recording and analysis of EGG are discussed. Thirdly, findings reported in the literature demonstrating the accuracy of EGG in recording gastric slow waves and gastric dysrhythmia are reviewed and discussed. The correlation of the electrogastrogram with gastric contraction is carefully discussed. Finally, applications of EGG in a few major areas are reviewed.
胃电图（EGG）是一种测量胃电活动的非侵入性方法。它于 1921 年首次被发现，并于 20 世纪 90 年代得到普及。EGG 具有吸引力，因为它是非侵入性的。然而，由于其非侵入性，EGG 的有效性和应用也存在争议。本综述的目的是讨论 EGG 的方法学、验证和应用。还将详细讨论 EGG 的优缺点。首先，介绍胃慢波及其与胃动力的相关性。综述了胃节律紊乱与胃动力障碍的关系。其次，详细介绍了胃电图的记录方法，并讨论了 EGG 记录和分析中的陷阱。第三，综述并讨论了文献中报道的 EGG 记录胃慢波和胃节律紊乱准确性的研究结果。仔细讨论了胃电图与胃收缩的相关性。最后，综述了 EGG 在几个主要领域的应用。
