[Anatomo-vectorcardiographic correlation in ventricular growth in congenital heart diseases].

Anatomo-vectorcardiographic correlations were studied in 59 cases of congenital heart disease. In the group with interventricular septal defect and pulmonary hypertensión, a statistically significant correlation between the thickness of the free right ventricular wall, at its outflow tract, and the inscription time of the vertex of the S loop, was found. In the group of Fallot's tetralogy, the segmentary hypertrophy of the right ventricle, which is the most frequent, explains very well the terminal portion of frontal and sagittal vectorcardiograms located below the 0 point. In the group with interatrial septal defect and pulmonary hypertension, a statistically significant correlation between the thickness of the antero-lateral superior third of the free right ventricular wall and the inscription time of the vertex of the S loop, was shown. In the group of congenital malformations with repercussion on the left ventricle (interventricular septal defect, patent ductus arteriosus and coarctation of aorta), a statistically significant correlation between the anatomical findings of a hypertrophied superior third of this ventricle and the inscription time of the vertex of the R loop, was observed.
