胃肠运动功能性疾病,或称胃肠动力性疾病(gastrointestinal motility disordef)是指一系列的胃肠运动功能失常(如胃动过速、胃动过缓、胃排空延迟、功能性肠梗阻和肠-胃反流等)所引起的临床表现。其中一部分起源于胃肠平滑肌肌电的异常变化[如消化间期综合肌电(IMC)Ⅲ相的缺如及传导异常等]。 Gastrointestinal motor dysfunction, or gastrointestinal motility disfunction, refers to a series of gastrointestinal motility disorders (eg, tachycardia, bradycardia, delayed gastric emptying, functional bowel obstruction And intestinal - gastric reflux, etc.) caused by the clinical manifestations. Some of them originate from the abnormal changes of gastrointestinal smooth muscle EMG [such as lack of interphagia IIIG and conduction abnormalities].
