随着数字化系统的广泛应用和其价格的相对降低,用磁盘或光盘记录脑电图,并长期保存,已经成为现实.这种记录有几个优点:它能减少多年的原始记录纸的存放空间;借助于它,人们通过选择导联组合、滤波、垂直尺度(增益或敏感性)和水平尺度(例如纸速)的方法从原始记录中选出部分脑电图进行复阅.最后,有了数字化记录,人们能在事后做进一步的数字处理.本推荐仅描述作为临床脑电图记录的数字化的最低技术标准.为便于兼容的记录能在脑电图室间任意交换,新记录数据的结构和格式标准由美国脑电图协会文件“不同的计算机系统间转换的数字化神经生理学数据的标准” 中专门列出.病人资料脑电记录的资料应该包括病人的姓名、出生日期、检查日期及有关的病人和实验室的识别号码.此外,还应包括随脑电信号一起而记录到脑电图纸的所有常规资料.在医生复阅脑电图后,最好将脑电图报告和脑电图信号(纸)一起保存.有关病人的识别资料在记录以后,如果发现错误或遗漏,应该可以纠正.记录中的识别资料
With the widespread use of digital systems and the relative reduction in their price, it has become a reality to record EEGs on disk or CD-ROM and save them for long periods of time. This recording has several advantages: It reduces the storage space for many years of original recording paper ; By means of which one selects the part of the EEG from the original record for review by selecting the lead combination, filtering, vertical scale (gain or sensitivity) and horizontal scale (eg paper speed) Finally, with Digital recording allows one to do further digital processing afterwards.This recommendation describes only the minimum technical standard for digitization of clinical EEG records. To facilitate the exchange of compatible recordings in the EEG room, the structure of the new recorded data And format standards are specifically set forth by the American College of Electroencephalographic Association document “Criteria for Digital Neurophysiological Data Transplanted Between Different Computer Systems.” Patient Information EEG data should include the patient’s name, date of birth, date of examination, and relevant Of patients and laboratories identification number.In addition, should also include all the EEG paper with EEG together with all routine information in the doctor After reviewing the EEG, it is advisable to save the EEG report together with the electroencephalographic signal (paper) .If the patient’s identification data is recorded, any errors or omissions should be corrected.
