• The angular range means the range of the direction, in which instantaneous vectors exist. The magnitude of the polar vector is one half of the integral of this angle weighed by square of the instantaneous vector, if the loop is on one plane. It was suggested that the angular range could be used for quantitative estimation of the inscription of the vector loop. The angular range of major vectors was evaluated by means of half maximal vectors. It was pointed out that the obtained value of the angular range might also be used for estimation of the loop area. Frank lead vectorcardiograms of 50 normal subjects and 76 patients with ventricular hypertrophy were examined with the above method in 3 planar projections. The half maximal vector itself was also examined with the QRS loop and found to be of some clinical values.
