[Relation system of electrocardiographic parameters in posterior myocardial infarction].
The polarcoordinates of the electrical heart vector in the groups of posterodiaphragmatic, postero-basal and extensive posterior myocardial infarctions were determined by the triaxicardiometer analogue computer. The ecg leads of Franks' system were numerically and graphically reconstructed from the digitalized polarcoordinates using formulas of connection between spherical polarcoordinates and rectangular Cartesian coordinates. Then the 12 conventional leads, by the use of coefficients were synthetized from the reconstructed leads of Franks' system and of the conventional leads were performed by the ODRA 1204 computer. So was created the connection system of the electrocardiological parameters, where the informative value of the polarcoordinates and the Cartesian coordinates-also mathematically-is exactly alike.
