本文对胃电的特征、胃电与胃运动的关系、影响胃电的各种因素等生理学的新进展作了简要的介绍。也提出了胃电的临床应用和目前存在的问题。胃电分为慢波和快波。慢波也称为基础电节律,是一种比较规律的在任何生理情况下都能记录到的电波,在切除神经组织后仍能节律地发生,因此是肌原性的;这种波发生后不伴有肌肉收缩,为具有自律性的纵行平滑肌细胞所特有。胃电快波是负载于胃电慢波之上或其后的一系列峰电位,是胃运动的动作电位。故只有在胃运动时才有。胃电慢波的节律决定着每组胃电快波和胃运动的节律。神经系统和胃肠道的激素都能影响胃电活动。但关于这方面的研究,目前还存在着很多问题。
This article gives a brief introduction to the new progress of physiology, such as the characteristics of gastric electrical, the relationship between gastric electrical activity and gastric motility, various factors affecting gastric electrical activity. Also put forward the clinical application of gastric electrical and the current problems. Stomach is divided into slow waves and fast waves. The slow wave, also known as the fundamental electrical rhythm, is a relatively regular electrical wave that can be recorded under any physiological condition and still rhythmically after removal of the nerve tissue and is therefore myogenic; after this wave has occurred Not accompanied by muscle contraction, is characterized by self-regulatory longitudinal smooth muscle cells. Gastric fast wave is a series of peak potentials that are loaded on or behind the slow waves of gastric electrical waves and are the action potentials of gastric motility. Therefore, only when there is stomach movement. The rhythm of gastric slow wave determines the rhythm of gastric fast wave and gastric motility in each group. Nervous system and gastrointestinal hormones can affect gastric electrical activity. However, there are still many problems about this research.
