众所周知 ,频率为 8～ 13Ｈｚ的脑波是健康成年人所具有的主要的基本节律。但在实践中 ,有些脑波频率虽属α节律 ,却不一定代表脑机能正常。本文选择首次脑电图 (ＥＥＧ)检查为 8～ 9Ｈｚ的慢α节律患者 10 0例 ,进行ＥＥＧ及临床的回顾分析 ,探讨其间的关系。1　资料与方法在 It is well-known that brain waves at a frequency of 8-13 Hz are the major basic rhythms that healthy adults have. However, in practice, although some brain wave frequencies are alpha rhythms, they do not necessarily represent normal brain function. In this paper, 100 cases of slow alpha rhythm patients who were examined by EEG for 8 ~ 9Hz were selected and analyzed by EEG and clinical retrospectively to explore the relationship between them. 1 materials and methods at
