脑电图纸上记录下来的是一种光滑规则和重复出现的曲线或是两个波重叠而成的多形态曲线。这种曲线单个出现时称为波,连续出现不到一秒钟则称活动,如连续出现超过一秒称为节律。波、活动、节律都是指波而言,只是数量的多少不同。一个波型从它的起点至返回基线的时间称作周期(用毫秒表示)。从波的起点至顶峰的高度称为波幅高度(用微伏μv表示)。一秒钟出现的周期数称为 EEG paper is recorded on the paper is a smooth rule and recurring curve or two waves overlap formed polymorphic curve. This curve appears as a single wave, appears less than a second continuous activity, such as continuous for more than a second called rhythm. Waves, activities, rhythms are waves, but the number of different. The time from a start of a pattern to its return to the baseline is called the period (in milliseconds). The height from the beginning of the wave to the summit is called the amplitude of the wave (expressed in μV μV). The number of cycles that occur in one second is called
