目的:观察功能性消化不良患者空腹体表胃电图(ＥＧＧ)变化情况。方法:对临床诊断为功能性消化不良的５０例患者行空腹体表ＥＧＧ描记(实验组)。对照组为３５例健康查体者,亦行空腹体表ＥＧＧ描记。将两组描记结果进行对比分析。结果:５０例功能性消化不良的患者中有３８例(７６%)体表ＥＧＧ异常,主要表现为胃电节律过缓或过速。而对照组仅有５例(１４．３%)体表ＥＧＧ异常。两组差异显著(Ｐ＜０．０５)。结论:空腹体表ＥＧＧ描记对功能性消化不良具有协助诊断意义,它对进一步了解胃动力紊乱性疾病的病理机制亦有帮助。
Objective: To observe the changes of fasting surface electrogastrogram (EGG) in functional dyspepsia patients. Methods: Fifty patients with clinically diagnosed functional dyspepsia underwent fasting epicardial EGG (experimental group). The control group of 35 healthy people, but also the fasting body surface EGG trace. The two sets of tracing results were compared. Results: Of the 50 patients with functional dyspepsia, 38 (76%) had abnormal EGG on the surface of the body, which was mainly characterized by transient or excessive electrogastrogram. While in the control group only 5 (14.3%) had abnormal EGG on the body surface. The difference between the two groups was significant (P <0.05). Conclusion: The fasting body surface EGG tracery is helpful to diagnose functional dyspepsia. It is helpful to further understand the pathological mechanism of gastric motility disorder.
