[Cartogram of 35 ECG leads in hypertrophy of the right ventricle of the heart].
Automatedly-reproduced cartograms of 35 electrocardiographic leads in 27 cases of isolated right-ventricular hypertrophy (RVH) were analysed in relation to the latter's roentgenocardiometric markedness, and the obtained results were substantiated in terms of spacial vectorcardiography. A direct correlation was established between cartographic and roentgenocardiometric data in cases of moderate RVH that was absent in marked RVH. The correlation between cartographic and vectorcardiographic parameters was, on the contrary, only slightly expressed in moderate RVH and high in marked RVH cases. These results can be attributed to specific anatomical structure of the hypertrophic myocardium at different stages of RVH formation, with either the outflow-pathway hypertrophy proper prevailing at early stages of hypertrophic development, or the right-ventricular free wall hypertrophy prevailing at later stages which result in irregular thickening of individual compartments and distortion of cavity size characteristics and geometrical properties of the right ventricle proper, as well as the displacement of the center of gravity and heart rotation round its own axes.
