[Value of vectorcardiography in the diagnosis of postero-septal infarct].

Posteroinferior infarction often complicated by the contemporaneous antero-septal necrosis due to anterior descending coronary artery critical stenosis. To confirm the value of VCG in the diagnosis of these two necrosis as regards ECG, the Authors have studied with echocardiogram, 19 patients with postero infarction, with or without inferior necrosis. The results were: frequent association of antero-septal infarction in postero-inferior necrosis; morphological and chronological VCG criteria in the diagnosis of postero-septal infarct; VCG use as bloodless method, to distinguish among the subjects with postero necrosis, the patients who must be subjected coronary angiography.
