Abstract
Until the mid-1980s. it was believed that the vectorcardiogram presented a greater specificity, sensitivity and accuracy III comparison to the conventional electrocardiogram. in the diagnosis of the different heart diseases. Recent studies revealed that the vectorcardiogram still is superior to the electrocardiogram in very specific situations, such as in the evoluation of electrically inactive areas. in intraventricular conduction disorders combined and/or in association to inactive areas, in the identification and location of ventricular preexcitation, in the differential diagnosis of patterns varying from normal of electrical axis deviation, in the evaluation of particular aspects of Brugada synchome, and in the estimation of the severity of some enlargements, among others.With the advent of computerized vectorcardiography, a technology that improves the processing and recording method; a future still promising is expected for this methodology.In the fields of education and research, vectorcardiography provided a better and more rational insight into the electrical phenomena that occurs spatially, and represented an important impact on the progress of electrocardiography. Although a few medical centers still use the method as a routine, we hope that the use of this resource will not get lost over time, since vectorcardiography still represents a source to enrich science by enabling a better morphological interpretation of the electrical phenomena of the heart.
