(1) the curves of the hypertrophied ventricle in Standardized Local Leads are characterized by increased amplitude of the initial deflection and delayed intrinsic deflection on the epicardial side (the praecordium and the diaphragmatic and basal ventricular portion in esophageal leads), and the increased amplitude of the electronegative initial deflection on the endocardial side (r. praecordium for the l. ventricle; l. praecordium and the lower auricular portion in the esophagus for the r. ventricle). (2) The T wave over the hypertrophied ventricle is inverted, when muscular hypertrophy occurs to a marked degree. This change of the final deflection may be considered as the result of increased polarization of the cell and tissue membrane by the organic changes (increase and thickness of connective tissue etc.), according to "Chain-doublets Theory (Maekawa)". When muscular hypertrophy is accompanied with relative lack of oxygen, the R-ST junction is deviated. (3) Studies of relationship between the limb lead patterns and Standardized Local Lead patterns on ventricular hypertrophy gave the conclusion that limb lead patterns are determined by (I) the magnitude of the potential, (ii) the conduction modus and (iii) the spatial position of each ventricle, and that, therefore, ventricular hypertrophy should be judged by Standardized Local Leads.
