自Alvarez于1922年报告从胃记录到胃电活动以来,许多电生理学家为此做了很多研究工作,证实了胃的平滑肌和心肌,骨骼肌一样,在它兴奋收缩前先有电活动。机体在不同状态下,胃平滑肌的电活动发生变异,有人利用它研究胃的生理和病理生理,并引向临床用于诊断胃部疾患和观察疗效。Sabakin试制成胃电图机,他用体表电极可记录胃电活动,经与胃粘膜电极记录的胃电活动相比较,证实两者测到的频率是一致的,其振幅体表电极较胃粘膜电极明显变小,因胃电活动通过一定距离地传导逐渐衰减所致,各
Since Alvarez’s report in 1922 on gastric electrical activity recorded from the stomach, many electrophysiologists have done a lot of research to confirm that gastric smooth muscle, like myocardium and skeletal muscle, has electrical activity before its contraction is excited. In different states, the electrical activity of gastric smooth muscle variation, it was used to study the physiological and pathophysiology of the stomach, and lead to the clinical diagnosis of gastric disorders and observe the effect. Sabakin try-made electrogastrograph, he used the body surface electrode can record gastric electrical activity, compared with gastric electrical activity recorded by gastric mucosal electrodes, confirmed that the two measured frequency is consistent, the amplitude of the surface electrode Gastric mucosal electrode was significantly smaller, due to gastric electrical activity through a certain distance from the conduction gradually attenuated, each
