The principle and method of ECG- and VCG reconstruction were outlined. The reconstructed VCGs of a normal and some hypothetical case of L.B.B.B., R.B.B.B., antero-lateral infarction and posterior infarction were comparatively demonstrated with the clinical cases of those VCGs respectively, and a good agreement in configuration was found between them. Four different lead systems, Grishman's, Frank's, the SVEC III, and the P III lead systems were examined with the lead vector of their three standard leads on the torso of a Japanese having a normal constitution by means of the torso model experiment. The three, Frank's, the SVEC III, and the P III lead systems were very close to each other in their componental lead vectors. In minor aspect, however, there was a noticeable difference in the Z axis component between Frank's and the SVEC III lead systems. The Z axis component in the former system was observed to become greater than that in the latter system as the location of the test dipole approached the sternum. The characteristic difference in the Z axis component between each system was also observed with some instantaneous vectors of reconstructed VCGs and clinical VCGs.
