用腔内电极或用经改进的无创伤技术测量人体胃电图(EGG)的方法已有文章作了介绍.这些方法只提供胃电活动的存在和胃电活动频率的信息,这些信息有助于胃动过速的诊断.但是没有一种方法能提供胃电活动传播方向和传播速度的信息,而这些信息有助于检查出如胃-食管回流、胃窦回流和胃壅滞这些不正常现象。作者用经皮电极和腔内
Methods of measuring intraoral electrodes (EGGs) with intraluminal electrodes or with improved noninvasive techniques are described in these articles, which provide information on the presence of gastric electrical activity and on the frequency of gastric electrical activity In the diagnosis of tachycardia, but none of them provide information on the direction and rate of transmission of gastric electrical activity, and this information helps to detect abnormalities such as gastric-esophageal reflux, gastric antrum reflux, and gastric lassitude phenomenon. The authors used percutaneous electrodes and intraluminal
