Octant vectorcardiography is based on two new principles--octants and peaks (Laufberger 1980, 1981, 1982). The octants divide the cardioelectrical space into eight parts. The peaks are characterized by the maxima of six sets recorded and printed by a computer. Special characteristics may be determined for the diagnosis of coronary artery disease, namely reversed rotation, the appearance of the fifth octant and successively deteriorating findings of the octant vectorcardiography examination. Electronic equipment was constructed providing automatic display of octants and peaks. From the results the state of the coronary artery disease can be stated immediately.
