Abstract

This excellent monograph is the result of more than ten years' studies on the distribution of the electrical field within the human body. The vectogram (VG) is said to express the complex electric phenomena of the heart more completely than the classic electrocardiogram. Theoretically, it indicates the spatial orientation of the average direction and, by its length, the algebraic sum of all the electromotive forces of the heart acting in any instant. The apparatus used by the authors is described. The "bipolar" method was employed, with leads in three planes, frontal, sagittal and horizontal, with one point in common, located in the right lower and posterior part of the torso. In the "unipolar" method, the vectogram is obtained by a combination of unipolar leads in the vertical, sagittal and transverse direction along lines which connect the center of the heart (determined by fluoroscopy) with the electrode.
