[About vectorcardiographic examination].
The clinical importance of the spatial exploration of the cardiac electrical phenomenon (vectorcardiography), which is a very useful integration of the analytical and limited electrical exploration (electrocardiography), is outlined here. Reasons inducing the mexican school to prefer the Grishman's cube method for the vectorcardiographic recordings of other more elaborate and complex systems, are explained. The former reflects in a more reliable way the sequence of myocardial depolarization and repolarization. Morphological and chronological aspects characteristic of the normal vectorcardiogram in the frontal, horizontal and sagittal planes, are described. Additionally some typical examples corresponding to the three main electrical heart positions are presented. The vertical position is frequent in children and longilineal persons, the intermediate position is common in adults and the horizontal one is observed in age people and brevilineal persons. Some vectorcardiographic aspects typical of myocardial necrosis, injury and ischemia are discussed, underlining the importance of the complementary elements given by vectorcardiography.
