説明
Our methods of computer applications in spatial analytico-geometrical analysis of VCG were described. Normal standards of the FRANK system VCG based on the quantitative analysis of 73 healthy middle-aged men were presented. New parameters, such as spatial linear, angular and areal velocities of QRS loops; spatial circumferences, spatial angles, and spatial areas of QRS loops were introduced for the quantitative descriptions of the VCG findings, and the normal data of these items were also presented. VCG of healthy middle-aged men were very similar with those of the healthy young men, although the magnitudes were slightly smaller in the former. It was suggested that the VCG criteria specific for the races are necessary for the clinical applications of VCG, because the analytic values were quite different between healthy Japanese and American men.
