近年来,脑电图检查技术又有一些新进展,现就部分内容简介如下。一、脑电遥测技术前几年,在国外少数大城市的脑电图研究中心,已试图利用民间有线电话线路进行市内、城乡和城城(相距240里以内)医疗单位间的6—8导程脑电遥测技术。但需在病人和脑电图检查室两处分别增设脑电讯号调频和解频装置,才能与电话线路配接使用。试验结果证实脑电记录并无失真,既使偶见电话拨号和开关等干扰讯号,但易被辩认,
In recent years, there are some new advances in electroencephalography, now part of the content is as follows. First, EEG telemetry A few years ago, a few large foreign cities EEG Research Center, has tried to use private landline telephone lines, urban, rural and urban (within a distance of 240) medical units between 6-8 Lead EEG telemetry. However, the patient and the electroencephalography examination room are required to add two EEG frequency modulation and frequency separation device, can be used in conjunction with the telephone line. Test results confirm that there is no distortion of EEG records, even occasional telephone dialing and switching interference signals, but easy to be identified,
