Examination of patients with dizziness has been performed with an original computer nystagmus analyzer which consists of an alternating current amplifier, analog-digital transformer, personal computer with special software. The technique of electronystagmography in optokinetic and bithermal tests was applied. The programs provide good quality of recording nystagmic reactions and protect from artefacts of different origin. All the nystagmic responses are measured with identification of the extremums indicating the beginning and end of each nystagmic cycle. The amplitude, duration and speed of the slow and fast nystagmic components are calculated both for the overall nystagmogram and its fragments. The computer analysis of nystagmograms provides rapid and accurate differential diagnosis of various types of vestibular dysfunction.
使用一台由交流放大器、模拟数字转换器和装有特殊软件的个人计算机组成的原装电脑眼震分析仪，对头晕患者进行了检查。应用了视动和冷热试验中的眼震电图技术。这些程序能提供高质量的眼震反应记录，并防止不同来源的伪迹干扰。所有眼震反应都通过识别每个眼震周期开始和结束的极值来测量。计算了整个眼震图及其片段的慢相和快相眼震成分的振幅、持续时间和速度。眼震图的计算机分析为各种类型的前庭功能障碍提供了快速准确的鉴别诊断。
