title: [Contributions of the Mexican electrovectorcardiography].
abstract: We narrate the main stages of the long journey that led to the structuring of modern electrovectorcardiography based on the fundamentals established by Willem Einthoven (1860-1927), who held the physiology chair of the Leyden University (The Netherlands), and presented his string electrocardiograph in 1901. The Mexican electrovectorcardiography became strong thanks to the endeavor of Dr. Demetrio Sodi Pallares, a disciple of F.N. Wilson of Ann Arbor. Dr. Sodi Pallares founded the Mexican School of Electrovectorcardiography, which was a cornerstone in the field and was widely recognized internationally for several decades. This fact is due to the rational and not empirical approach to the electrical exploration of the heart, thanks to the application of the inductive-deductive Galilean procedure. It was then possible to obtain these results, through the study of myocardial depolarization and repolarization processes, under normal conditions and with bundle branch block, performed by Dr. Gustavo A. Medrano and collaborators, in the 1950 decade. The electrovectorcardiographic manifestations of the non complicated myocardial infarct were the object of studies, as well as those of the infarction complicated with rhythm and conduction disorders. Likewise, proximal and distal or peripheral blocks were studied. The current disciples of that School are now studying of cardiac arrhythmias with promising results.
