The Excitatory Process in the Dog's Heart Part II The Ventricles . Fig. 15.—A diagram showing the ventricular wall in section and the paths travelled by the excitation wave, from the point of stimulation to the external and internal 16.—A diagram illustrating an arrangement of contacts, with the stimulating electrodes placed near to, and far from, the proximal contact. When the ventricle is excited at S2 the interval between the appearance of the excitation wave at P and D is shortened. The distance of the point of stimulation from the contacts shows its influence in anexperiment of a somewhat different type. Two contacts (P and D) are placed acrossthe right ventricle (fig. 16), and a point of stimulation is chosen a little to the left(lying usually over the trabeculated region or near its border) and in line with them(S1). The time interval between the contacts is ascertained for. natural and excitedbeats; the latter, as usual, exceeds the former. The stimulating electrodes are nowmoved along the same line to the left border
