Many reports have been published on the morphology of the electrocardiographic patterns in chronic cor pulmonale, but no available report has been described for the spatial characteristics of the ventricular vectors in chronic cor pulmonale as determined by the orthogonal systems. This study was intended to investigate the spatial changes of the electromotive forces of the heart and to clarify the process how the typical patterns of the right ventricular overloading fully developed in chronic pulmonary diseases. 190 cases with chronic pulmonary diseases were classified in 3 groups as shown in table 3. Group I (84 cases) : normal in pulmonary functions as well as cardiovascular examinations. Group II (66 cases) : pulmonary functions were moderately impaired. Group III (40 cases): pulmonary functions were severely impaired. Vectorcardio-graphic scalar electrocardiograms of the orthogonal systems(FRANK and SVEC-III) and of the cube systems(GRISHMAN and KIMURA)as well as the standard 1 2 leads electrocardiograms were recorded in all cases. Ventricular electromotive forces were expressed as azimuth, elevation, magnitude of mean QRS and T vectors and QRS-T angle using SIMONSON'S Vector analyzer. The results obtained were as follows : I . Electrocardiographic criteria for the diagnosis of the right ventricular hypertrophy proposed by various authors were evaluated concerning their positivities as well as false positivities. SOKOLOW'S criteria showed high incidence of false positivity (32%) in Group I, and MILNOR'S criteria showed low incidence of positivity (2.5 %) in Group III. MORI's criteria appeared to be most useful clinically among these criteria, because it had low false positivity (3.5 %) and high positivity (20%). 2 Electrocardiographic pentalogy of pulmonary emphysema proposed by WASSERBURGER were corrected quantitatively near the normal limits as shown in table 5. These corrected pentalogy and other electrocardiographic findings, which were occasionally en-countered in pulmonary emphyserna, were also examined concerning their positivities as well as false positivities as shown in table 6. It was shown that MACRUZ'S index was not adequate for clinical use because it yielded high incidence of false positivity (16.7 %). 3. Vector analysis of these subjects indicated that the characteristic changes of the spatial ventricular vectors in the right ventricular overloading due to pulmonary ventilatory impairement were marked decrease in azimuth and elevation of QRS and T vectors and decrease in magnitude of T vector.
