Abstract
1. 1. The planar electrocardiographic indices (angular directions of mean frontal and sagittal QRS and T vectors) and spatial indices (angle between mean spatial QRS and T vectors, mean spatial QRS and T vector loci) of 102 normal, youthful adults were determined with respect to a corrected frame of reference. These results were compared with similar determinations made on the same subjects with respect to an uncorrected frame of reference. 2. 2. All of the planar indices, and the mean spatial QRS-T angles exhibited some reduction of scatter, ranging from slight to moderate, within the corrected frame of reference. 3. 3. The mean spatial QRS and T vector loci exhibited slightly less scatter and better coefficients of correlation within the uncorrected frame of reference. 4. 4. The corrected frame of reference does not appear to possess sufficient merit to warrant its routine application to the analysis of mean QRS- and T-vector orientation. © 1957.
