title: Maximizing the informational content of vectorial data in the electrocardiogram.
abstract: Scalar electrocardiograms contain a great deal of vectorial data. The informational content of these data can be maximized by treating each angle as a point on a plane whose distance from the origin is equal to the magnitude of its vector. These points can be resolved into their horizontal and vertical coordinates. The coordinates are linear values and can therefore be subjected to standard statistical methodology.
