体表胃电图的电极定位研究综述

Research on the Electrode Orientation of Electrogastrogram

综述国内外在体表胃电图表面引导电极安放位置的研究状况及目前常用的定位方法,指出体型、性别、年龄和胃下垂等影响胃形态和位置的因素.同样会影响胃电图表面引导电极的安放位置。进行电极定位时必须根据这些影响因素加以修正,确保不同个体的电极定位均能落在胃同一部位体表投影处。

This article describes the ways of the electrode orientation of the electrogastrogram (EGG)in China and abroad. The various electrode orientation were found in different habitus、sex、ages and gastroptosis. In order to get the correct position of electrode orientation, the different standards of orientation must be used in different people. The article recommened a new method at last. The habitus must be distinguished at first. The suitable digits of the electrode orientation can be used secondly.
