[New heart wall terminology and new electrocardiographic classification of Q-wave myocardial infarction based on correlations with magnetic resonance imaging]

A dogma is any point of doctrine that is believed to be unquestionable and certain. In this sense, in electrocardiographic diagnosis, the dogma that there was a posterior wall of the left ventricle and that post-infarction patients in which a tall R wave appeared in V1 through V2 had an infarction of that wall was considered certain and unquestionable. Besides, the presence of QS morphology in VL was considered as a manifestation of a high lateral infarction. Lastly, it was believed, ever since Myers et al1-3 anatomopathologic correlation study, in the 1940s, that the localization of a Q wave infarction was as follows: Q in V1 through V2 indicated septum infarction, V3 through V4 anterior, V5 through V6 low lateral, I through VL high lateral, and II, III, VF inferior.
