[Multipolar image of the heart in patients after myocardial infarction].

This paper regards 136 cases of cardiac ischaemia including 93 post-infarction cases and 43 with post-effort angina pectoris. The patients with history of infarction were divided according to its electrocardiographic++ location. The groups of subjects were submitted to multipolar electrocardiographic recording from chest surface by means of a multi-electrode network (diamentoid) introduced to vectorcardiography by the Kowarzyk method. The QRS complex divided into 8 equal sectors served as the basis for calculating, among other things of the non-ipolarity index (km) and its graphical representation. The ++non-dipolarity index tends to be especially high in patients with recurrent and large infarction, it was increased in angina pectoris.
