Summary:There are so many kinds of vectorcardiographic lead systems that a great deal of inconvenience arises in the clinical use of vector cardiography. We have already reported a mutual transformation theory in vectorcardiogram (VCG) by which a VCG of any lead system could be transformed into a VCG of any other lead system without moving the electrodes among VCG lead systems of McFee, Schmitt, Frank, Grishman, Kimura and Wenger-Hupka. According to the theory, the authors devised a VCG coordinate changer, which can perferm automatically the above mentioned mutual transformation of VCGs with the aid of the coefficients of our transformation equations. Moreover, with the use of the coordinate changer, the loops of VCG, as a whole, can rotated to various directions. Therefore, VCG can freely observed from optional directions of a human body.
