1921年,Alvarez首次报道从胃能记录到电活动。随后,许多学者用不同手段,在不同动物上,其中包括人,对胃电产生的机制、生理意义及影响因素进行了深入的研究。目前,倾向认为胃的电活动确能较准确地反映胃功能,可以作为胃活动的指标。胃电的类型及其生理意义从胃的肌层记录到的电位变化可分为两种类型。一种是规则、慢节律、周期性的去极化性电位,称为慢波。它始终存在于平滑肌上,即使在空腹情况下也仍然出现。它的每一周期由两部分组成
In 1921, Alvarez first reported the recording of electrical activity from the stomach. Subsequently, many scholars used different means, in different animals, including people, on the mechanism of gastric electrical, physiological significance and influencing factors in-depth study. At present, the tendency is that gastric electrical activity can accurately reflect the gastric function, can be used as an indicator of gastric activity. The type of gastric electrical and physiological significance recorded from the gastric muscle potential changes can be divided into two types. One is the rule, slow rhythm, periodic depolarization potential, known as the slow wave. It is always present on the smooth muscle, even in fasting situations. Each cycle consists of two parts
