• In this paper, I applied the results of potential measurements in previous report to the discussion of various problems in the clinical electrocardiogram and the vectorcardiogram. 1) From the potential value due to the activation of each unit muscle region of ventricle, I could determine the most effective ventricular region to each point of unipolar chest lead and found these results coincided well with those of Wilson and of Rosenburg. 2) I knew that the Vectorpolyography of Toyoshima was the moset excellent method to represent the electrical heart axis as the vector when we compared the manifest resultant vectors by various ground to select the leading points of Vectorpolyography in each plane as follows. a) Frontal plane. The eight points having same distance each other on the circle drawn on the back surrounding D_9 with radius 10 cm. b) Horizontal plane. The eight points surrounding the trunk in same distance at the navel level. c) Sagittal plane. Four opposite points on the preaxillar and postaxillar line at the 2-nd and 8-th intercostal levels. 3) I supposed two processes of ventricular activation modifieing the assumptions of Lewis and of Barker and traced Vectorpolyogram, unipolar chest lead and standard limb lead electrocardiogram by calculation following to these processes. The results of these calculation were resembled closely with those of vectorcardiogram and electrocardiograms of normal adult. 4) In the Vectorpolyograms obtained by calculation, the initial direction of QRS loops of ventricular premature beat were coincident well with direction of inward normal at the stimulated point like as the experimental results of Toyoshima and Yamada on toad heart. 5) The unipolar chest lead tracings, derived as a scaler projection of horizontal vectorcardiogram, did not correlate so close with actual unipolar chest lead tracings as Lasser and his coworkers noted.
