METHODS: According to the RomeⅡcriteria, patients with FD were classified into 3 subclasses. From each subclass, 10 patients were randomly chosen in this study. 10 Healthy volunteers were used as normal control. All the patients and volunteers underwent electrogastrogram examination and gastric emptying test. Gastric emptying test was performed using 99Tcmlabelled solid food. Patients with FD were divided into 2 groups according to the results of gastric emptying test: normal gastric emptying group and delayed gastric emptying group. Data were collected accordingly and statistic analysis was performed. RESULTS: ① 18 patients showed gastric emptying delay. In patients with FD, postmeal average amplitude (AP) and △AP reduced significantly (Plt;0.05), compared with the control. However premeal, post meal average frequency and premeal AP did not show significant changes（Pgt;0.05）; ②In FD patients with normal gastric emptying, 41.7% showed abnormal electrogastrogram; ③ In the FD patients with delayed gastric emptying, 83.3% were abnormal in electrogastrogram and their postmeal AP and △AP decreased significantly（Plt;0.05）. However, premeal and post meal average frequency, premeal AP did not show significant changes（Pgt;0.05）. CONCLUSION: Motility disturbance of stomach plays an important role in the pathogenesis of FD. Electrogastrogram and gastric emptying test have a good consistency in determining FD. 　　【Keywords】 functional dyspepsia; electrogastrogram; gastric emptying 　　【摘要】 目的: 通过胃电图与胃排空检测，研究功能性消化不良(functional dyspepsia, FD)的发病机制. 方法: 以FD患者为观察对象，依据罗马Ⅱ标准，将符合纳入标准的患者分为3个临床亚型，每型患者随机取10人为一组，并以10名健康志愿者作为对照组，分别做胃电图及胃排空检测. 胃排空检测后，再将30例FD患者分为2组，胃排空正常组和胃排空延迟组. 利用胃电图仪记录胃电变化，通过99Tcm标记的固体餐检测胃
