The author calculated the direction of the electric charge of the hearts from the QRS-groups in the standard EKG of ventricular ES by means of Madia-wee's orthogonal isosceles triangle coordinates. The ES, the direction of which begins at the right of ther epresentative direction normal systole, and turns to the" left over it, and ends on the left of it, happens from the right ventricle, and vice versa. The ES happens near septiventriculi, when the rotation is small: and it happens near the base of the heart, when it is large. All above are proved easily both by the consideration that the abnormal stimulation is transmitted by the specific muscular system, and stimulates all the ventricles, and by the consideration about the rotation in the direction of the electric charge thus caused-through Prof. Mackawa's "Chain-doublets" Theory.
