Abstract
  1. The slow potentiel changes of the base line of the electrocardiogram recorded by cutaneous electrodes, here called EGEG (electrogastroenterogram) have been recorded simultaneously with the electromyogram and pressure variations of the stomach antrum. 2. Periodic fluctuations of EGEG, 400 microV amplitude, were correlated with activities of the antrum EMG consisting of 3 to 6 mV spikes superimposed on slow wave of depolarization, and with gastric intraluminal pressure of 5 to 7 cm of water. 3. An anticholinergic drug abolished all those activities. A gastric contracture flattened the EGEG. 4. Rhythmic distensions of the antrum induced a synchronous modulation of EGEG, the magnitude of which was correlated with the amplitude of distension. These result suggest that the origin of EGEG is essentially the movements of stomach.
摘要
  1. 用皮肤电极记录的心电图基线的缓慢电位变化,在此称为EGEG(胃肠电图),已与肌电图和胃窦压力变化同时记录。2. EGEG的周期性波动,幅度为400微伏,与胃窦肌电图的活动相关,胃窦肌电图的活动由叠加在去极化慢波上的3至6毫伏尖峰组成,也与5至7厘米水柱的胃腔内压力相关。3. 一种抗胆碱能药物消除了所有这些活动。胃挛缩使EGEG变平。4. 胃窦的节律性扩张引起EGEG的同步调制,其幅度与扩张幅度相关。这些结果表明,EGEG的起源本质上是胃的运动。
