This paper presents the operation of a digital computer program, VECTAN II, for the spatial analysis of the vectorcardiogram (VCG). The program incorporates a unique waveform recognition algorithm based on the spatial vector length which has been shown to perform better than previous algorithms. The waveform analysis employed by the program considers the vectorcardiogram as a three dimensional entity rather than as scalar or planar representations. VECTAN II is designed chiefly to measure and quantify the VCG response of normal subjects to a controlled stress by analyzing one VCG complex every five seconds throughout a long experiment. The program has been used to analyzeom the NASA Johnson Space Center Cardiovascular Laboratory, from the pre- and postflight medical examinations of the Apollo 15, 16 and 17 crewmen, and from onboard Skylab experiments.
本文介绍了用于心电图（VCG）空间分析的数字计算机程序VECTAN II的操作。该程序采用了一种基于空间向量长度的独特波形识别算法，该算法已被证明比以前的算法表现更好。该程序采用的波形分析将心电图视为三维实体，而非标量或平面表示。VECTAN II主要设计用于通过在长时间实验中每五秒分析一个心电图复合体，来测量和量化正常受试者对受控压力的心电图反应。该程序已被用于分析美国国家航空航天局约翰逊航天中心心血管实验室的数据、阿波罗15号、16号和17号机组人员飞行前和飞行后的医学检查数据以及天空实验室的机载实验数据。
