Maekawa's Standardized Local Leads are relative unipolar (chest and esophageal) leads, and are characterized by examining the relation of position between the heart and the exploring electrode. By this method the ventricular curves in the esophageal leads have been investigated theoretically. On any point on the left auricle the ventricular vector is observed from the electronegative side, also als the electronegative potential. Near the lower pole of the left auricle (ca. 38cm from insicur-tooth) the ventricular initial deflection is of the maximum amplitude, and that electronegative deflection represents the potentialvariations in the apex and the right ventricle, and that electropositive deflection represents the potentialvariations in the posterior wall of the left ventricle. The local potentialvariations on the posterior wall of the left ventricle can be led unipolarly not only on the basal portion (ca. 40cm) but on the diaphragmatical surface(ca. 46cm), especially in the case of the left ventricular hypertrophy.
