一、导言许多疾病与胃运动功能异常有关,如胃溃疡、食道返流、胃炎、迷走神经切断综合症及胃律过速等,因此临床上常通过对胃机械运动和胃电测量判定胃运动功能。但目前临床所使用的方法均是有损伤的,需要通过外科手术将电极或压力传感器置入体内,或通过一合适的记录管经由口腔插入体内。类似于心肌的去极化电压可以通过恰当放置的体表电极记录得到,也可在人躯干上
I. INTRODUCTION Many diseases are related to dysfunction of gastric motility, such as gastric ulcer, esophageal reflux, gastritis, vagotomy syndrome and gastric tachyarrhythmias. Therefore, gastric motor function and gastric electrogastrogram . However, at present, the methods used in clinic are all impaired. The electrodes or pressure sensors need to be surgically inserted into the body or inserted into the body via the oral cavity through a suitable recording tube. Depolarization voltages similar to those of the myocardium can be recorded by properly placed body surface electrodes and also on human torso
