消化间期综合肌电(IDMEC)是在空腹情况下,在慢波电活动的基础上,以周期性峰电活动为特征的综合肌电活动。血浆中游离脂肪酸(FFA)浓度变化是机体代谢过程中比较敏感的因素,与消化吸收过程紧密相关。因此,我们用狗进行慢性实验,在十二指肠浆膜面缝植三对电极,记录空腹时 Integrated digestive period myoelectricity (IDMEC) is a comprehensive myoelectric activity characterized by periodic peak electrical activity on the basis of slow-wave electrical activity under fasting conditions. Changes in plasma concentrations of free fatty acids (FFA) are more sensitive to the body’s metabolic processes, which are closely related to the process of digestion and absorption. Therefore, we conducted chronic experiments with dogs, sewed three pairs of electrodes on the serosal surface of the duodenum and recorded fasting
