Octant vectorcardiography and its data basis.

The present communication is a continuation of the previous report published in this journal [Physiol. bohemoslov., 29: 481, 1980]. It presents further information on the practical use and evaluation of the octant vectorcardiography method. The description starts from the elementary table set up according to the Frank lead system. All cases may be classified alpha-numerically into the data bases by means of a newly introduced concept - the octant. The data include 250 cases after myocardial infarction, supplemented by further information on the integration of peaks. In this way, even widely different cases can be compared in general. In advanced cases of coronary artery disease, an octant labelled in our terminology as the fifth octant, has been defined. The method brings new information about cases after myocardial infarction and it helps to determine the progress of the disease.
