为了观察西沙比利治疗老年功能性消化不良病人的胃电频谱改变。对57例（60—71岁）病人进行了治疗前后的体表胃电图检测。结果，治疗后胃动过缓组病人胃体、胃窦主频（FP）显著升高（P＜0．01），振幅（AP）明星升高（Pb＜0．05、Pa＜0．01），胃动过速组病人的胃体，胃窦平均过零频率（F2）明显下降（Pb＜0．01、Pa＜0．05）．胃节律紊乱组病人胃体．胃窦主频（FP）明显升高（Pb＜0．01．Pa＜0．05），频谱倍率（m）也明显升高（P＜0．05），而平均过零频率（F2）均明显下降（P＜0．05），结论，西沙比利治疗老年功能性消化不良，能显著提高病人的胃电主频．纠正胃电的节律紊乱。
In order to observe the cisapride treatment of elderly patients with functional dyspepsia gastric electrical spectrum changes. 57 cases (60-71 years old) before and after treatment of the body surface electrogastrogram detection. Results After treatment, the frequency of gastric and gastric antrum significantly increased (P <0.01) and the amplitude of star (AP <0.01, P <0.01) ). The mean zero cross frequency (F2) of gastric body and gastric antrum in patients with tachycardia was significantly decreased (P <0.01, Pa <0.05). Gastric disorders in patients with gastric disorders. The frequency of gastric antrum (FP) was significantly increased (Pb <0.01.Pa <0.05) and the spectral magnification (m) was significantly increased (P <0.05) (P <0.05). Conclusions: Cisapride treatment of functional dyspepsia in elderly patients can significantly improve the frequency of gastric electrical activity in patients. Correct gastric rhythm disorders.
