The orthogonal electrocardiography was a further development of Einthovens conception of electrocardiography. It eliminates the redundancy of the 12-lead ECG and offers a more precise and illustrative image of the model of an equivalent dipole. It was the prerequisite of the development of vectorcardiography. It improves the diagnostic performance of electrocardiology, especially by decreasing the spread of parameters used to characterize normal cardiac electrogenesis. It may be assumed that clinical electrocardiography will not petrify its standard 12-lead system but will utilize the possibilities offered by the more rational lead systems of orthogonal electrocardiography, as well as its enrichment by vectorcardiographic presentation of the cardiac electric field.
