慢性胃炎EGG特异性波形的研究

Research of Specific Wave Figures of EGG in Chronic Gastritis

根据在不同胃病状态下记录到的胃电图（Ｅｌｅｃｔｒｏｇａｓｔｒｏｇｒａｍ．ＥＧＧ）特异性波形为参考诊断标准，比较了全国现行的以ＥＧＧ频率、波幅为主要参考诊断标准对慢性浅表性及慢性萎缩性胃炎的临床诊断准确率。结果显示，以ＥＧＧ中低平小快波作为浅表性胃炎、低平慢波作为萎缩性胃炎的诊断指标，其诊断准确率明显高于现行的参考诊断标准（Ｐ＜０．０１）。

The diagnostic standard of electrogastrogram(EGG) now extensively used in our country is characterized by changes in frequency and altitude of the EGG(FAEGG), which proved short on specificity in diagnosing different gastric disorders. We found in our previous research work that besides the changes in fequency and altitude of EGG, there were also some specific wave figures of EGG(SWEGG) in patients with gastric disorders. This paper compared the differential diagnostic rates in gastric diseases of FAEGG and SWEGG.Our observations suggested that the EGG of patients with superficial gastritis was characterized by low flat quick waves,while that of patients with atrophic gastritis by low flat slow waves. Using these SWEGG in diagnosing the superficial and atrophic gastritis was significantly superior to using FAEGG(P<0.01)
