PublicationOn T waves normal in size and direction but abnormal in contour( 1949-01-01)
;Alzamora-Castro V.Subiría R.In normal subjects the polarity and contour of the T waves are relatively constant. Atypical T waves of normal polarity occur only occasionally in the tracings of normal subjects, but are common in the electrocardiograms of patients with heart disease. In many instances the behavior of these atypical T waves and the previous or subsequent clinical status of the patient indicate that the myocardium is abnormal. During carotid sinus stimulation and after long postextrasystolic diastoles, many of these atypical upright T waves become inverted. On the other hand, many inverted T waves are converted into atypical upright T waves by exertion or angina pectoris. In some cases atypical upright T waves furnish the only objective evidence that the heart is not normal. © 1949. -

PublicationParietal focal block; an experimental and electrocardiographic study( 1953-01-01)
;ALZAMORA-CASTRO V. ;ABUGATTAS R. ;ZAPATA C. ;SANTA-MARIA E. ;BINDER T. ;SUBIRIA R.PAREDES D.A method of producing focal ventricular block is described. The sequence of the electrocardiographic variations is ascribed to changes in the velocity and direction of the excitatory process in the ventricular wall. The epicardial electrocardiograms resemble those considered indicative of ventricular hypertrophy or of "incomplete" or of "complete" bundle branch block. When the focal block is pronounced a positive deflection appears in the cavitary tracing. The ventricular blocks can be subdivided into "conduction blocks" and "fiber blocks," the former produced by the delay of the stimulus in the specialized conduction system and the latter produced by the delay of the excitatory process in the ordinary heart muscle. -

PublicationThe three main vectors of the ventricular activation process in the normal human heart. I. Its significance( 1955-01-01)Tranchesi J.A study of the ventricular activation process (V.A.P.) at the body surface of normal subjects has been carried out by means of multiple simultaneous electrocardiographic leads. In order to reduce the discrepancies between real and calculated vectors, the vectorial analysis was facilitated by means of a plastic model in which the form of the thoracic cage as well as the location of the apparent "electrical center" was particularly considered. Three main instantaneous vectors corresponding to the V.A.P. are described. The first vector ("vector 1" or "septal vector") orients always forward and, as a rule, to the right; it represents early septal electrical forces. The second vector ("vector 2i" or "left ventricular vector") points to the left, downward, and backward, toward the free left ventricular wall. It corresponds to the predominant electrical activity originated in this ventricle. The third vector ("vector 3" or "basal vector") goes, usually, backward, to the right, and upward. It represents the deplorization of basal regions of the ventricular mass, including the septum. These three vectors are inscribed, on an average, at 0.010, 0.040, and 0.064 second, respectively, after the onset of the QRS complex. The determination of the three vectors from the scalar curve permits one to follow the spatial sequence of the ventricular activation process and to infer the potential variations at different points of the body surface. © 1955.

PublicationThe electrocardiogram in ventricular septal defect: Scalar and vectorial analysis of thirty-two cases( 1955-01-01)
;Marsico F. ;Tranchesi J. ;Limón R.Sodi-Pallares D.The electrocardiographic characteristics of thirty-two cases of ventricular septal defect have been analyzed. In the majority of cases the electrocardiographic pattern is diagnostic or strongly suggests this congenital defect. © 1955. -
