Vectorcardiographic Signs of Biventricular Hypertrophy

“…It could therefore be concluded that hypertrophy of the free wall of the right ventricle causes a change in the afferent limb of the QRS loop. Such changes were also observed by other authors (2,47). Cabrera (8) suggests right ventricular hypertrophy if the QRS loop on the transversal plane shows a prominent and neat S loop oriented dorsally and to the right.…”

“…The QR loop of the transversal as well as the sagittal planogram tends to loose its Q component (4,19,20,47).…”

“…It is generally accepted that hypertrophy of the left ventricle induces a turn of the maximum QRS vector dorsal to the left and slightly cranial (4,22,47). This vector displacement, however, is not distinct enough to serve as a diagnostic criterion for left ventricular hypertrophy, for rapid and steep dorsal deflection is frequently seen in young people, showing a pronounced "proxim ity effect" (19,20).…”
