Abstract
The spatial vectorcardiograms of 114 normal subjects over the age of 40 years have been studied. Differences in the form, orientation and magnitude of the QRS loops of these records and those of younger normal subjects recorded with the same techniques were found. The study represents a further step in defining the normal spatial vectorcardiograms.Keywords
