Effect of physical stress to electrogastrogram

As a result of an experiment directly guided from the gastric membrane side or gastric tunica serosa ventriculi side, electric activity of the stomach is generated at 3 cycle per minutes (3cpm) from the pacemaker near the greater curvature of the stomach side in the stomach upper part 1/3, and being spread to a pylorus side is confirmed. However, in the general clinical setting, it is very difficult to record electric activity from the gastric membrane side or gastric tunica serosa ventriculi, and the clinical application is restricted. On the other hand the method of recording electric activity of the stomach accompanied by stomach movement from the abdominal walls is called electrogastrography (EGG), and we can, record it now comparatively easily because of the progress of technology in recent years. Thus, we performed EGG measurement under various situations. Consequently, we discovered whether stress has a certain influence on the stomach activities.
