The number of data acquired in electrophysiology and the need for immediate analysis and interpretation justified the use of computerized signal acquisition and -analysis. Since such techniques are well known and established in computerized perimetry, the user of EOG, ERG, and VEP will profit from such an approach.
A computer program for signal acquisition and -analysis of clinical electrophysiology is described. The software is written in BASIC for IBM compatible PC/XT/AT computers. The program supports all electrophysiological examinations (EOG, ERG, VEP). It contains a subroutine for automated EOG recording and -analysis, allows measurements of amplitude and latency of standardized Ganzfeld-ERG and pattern-ERG. Options for recording and analysis of further stimuli are prepared. The possibility of determination of area under the curve is implemented. In the VEP subroutine evaluation of amplitude, latency, area under the curve, and Fast-Fourier-Transformation--necessary for steady-state-VEP--is installed.
The program demonstrates that with the now available low cost Personal Computer technology it is possible to build up individual software systems for clinical electrophysiology supporting and optimizing all recording, analysing, and administrative procedures.
在电生理学中采集的数据数量以及对即时分析和解读的需求，证明了使用计算机化信号采集和分析的合理性。由于此类技术在计算机化视野检查中已广为人知且已确立，眼电图（EOG）、视网膜电图（ERG）和视觉诱发电位（VEP）的使用者将从这种方法中受益。
描述了一种用于临床电生理学信号采集和分析的计算机程序。该软件用BASIC语言编写，适用于与IBM兼容的PC/XT/AT计算机。该程序支持所有电生理检查（EOG、ERG、VEP）。它包含一个用于自动眼电图记录和分析的子程序，可测量标准化全视野视网膜电图（Ganzfeld-ERG）和图形视网膜电图（pattern-ERG）的振幅和潜伏期。还准备了记录和分析其他刺激的选项。实现了测定曲线下面积的可能性。在视觉诱发电位子程序中，安装了对振幅、潜伏期、曲线下面积以及稳态视觉诱发电位所需的快速傅里叶变换进行评估的功能。
该程序表明，利用目前可用的低成本个人计算机技术，有可能构建用于临床电生理学的个性化软件系统，以支持和优化所有记录、分析及管理程序。
