Biophysical Model for Beat - to - Beat Variations of Vectorcardiogram

For a realistic biophysical model, a linear deformation of the myocardium lead to a linear transformation of the orthogonal electrocardiosignals under the condition of topological invariability of the depolarization and repolarization processes in the myocardium. Certain relationships have been found between the linear transformations in the physical and functional spaces. Several practically important conclusions follow as a logical consequence of these statements.
