The periodicity of paroxysmal wave complexes in EEG after acute cerebral anoxia with special reference to the dynamics of period duration (alteration of Zeitmass) is described in case 20 hours before isoelectric tracing. The completely asynchronous feature of paroxysmal events within certain limits of period duration in both hemispheres is a rare condition. Late and pure cortical electrogenesis is suggested. Short and long EEG- periods in similar and different pathological processes and functional states are compared with respect to topography of lesions. Subcortical interactions and extraneuronal influences upon periodicty are discussed. The parameters "complex wave and periodicity" in EEG and the dynamics respectively are a matter of serial investigations for better understanding pathophysiology and prognostic value.
在急性脑缺氧后脑电图中阵发性波复合体的周期性，特别提及周期持续时间（时间单位改变）的动态变化，这是在等电位描记前20小时的病例中描述的。在两个半球周期持续时间的特定范围内，阵发性事件完全异步的特征是一种罕见情况。提示存在晚期和纯皮质电活动。针对病变部位，比较了相似和不同病理过程及功能状态下脑电图的短周期和长周期。讨论了皮质下相互作用以及神经外因素对周期性的影响。脑电图中的“复合波和周期性”参数及其动态变化是一系列研究的主题，以便更好地理解病理生理学和预后价值。
