A special type of delta waves with a duration of 1-3 sec which, because of their saw-tooth or zed shape in the EEG, we have named 'zeta waves' has been described. They occur particularly in cases with rather severe brain lesions, usually with an acute or subacute onset and a space occupying character. In a period of 2 years during which 2500 EEGs have been reported we have seen zeta waves in 20 patients in whom 76 EEGs have been recorded. The characteristics of these waves and the types of lesions with which they occurred are described. The importance of an adequate recording technique for proper presentation of this EEG pattern is emphasized.
一种持续时间为1 - 3秒的特殊类型的δ波已被描述，因其在脑电图中呈锯齿状或Z形，我们将其命名为“ζ波”。它们特别出现在脑损伤相当严重的病例中，通常起病急性或亚急性，具有占位性特征。在报告2500份脑电图的两年期间，我们在20例患者中看到了ζ波，共记录了76份脑电图。描述了这些波的特征以及它们所出现的病变类型。强调了采用适当记录技术以正确呈现这种脑电图模式的重要性。
