Abstract
The differentiation between normal and abnormal changes in conventional electrocardiography is substantially improved by consideration of normal age trends. For clinical application of spatial vectorcardiography, consideration of age trends is equally important. On the basis of statistical evaluation of magnitude, azimuth and elevation of mean spatial QRS and T vectors in 105 healthy young men and 178 healthy older men, upper and lower limits were determined for each age group. The age differences were highly significant for all items of vector analysis.
