Abstract
From the means and standard deviations of the coordinates of the spatial QRS and T vectors in 178 normal middle-aged men, preliminary normal range limits were calculated for the total group, three positional subgroups, and three relative body weight groups. The superiority of spatial vector analysis over analysis of the scalar electrocardiogram made it possible for the first time to investigate meaningful correlations between electrocardiographic variables, such as the relationship between the magnitude of QRS and T vectors. The relationship between fundamental constitutional variables and spatial vectors was also investigated as background necessary for the diagnostic use of spatial vectors.
