Axis Concept in Body Surface Mapping

Abstract

The axis concept is well known both in evaluation and in documentation of Ecg and Vcg for many years. In the Einthoven Ecg the horizontal axis left to right gives the main axis, to which the vector in the frontal plane will be referred in angle and in magnitude. In every kind of measurement of the orthogonal Ecg and in the Vcg the parameters, which are very often used in diagnostics and in documentation are the angles of azimuth and elevation and the spatial magnitude of the vector. The normal values and the diagnostic criteria are very well documented in a large number of patients and collectives. This holds also for the so called polarvector, the perpendicular vector of all directly measured vectors.
