[Relation between left-ventricular insufficiency and necrotic mass in myocardial infarction, determined by analysis of the QRS complex].

A noninvasive method, based on the analysis of QRS parameters from 10 of 12 standard ECG leads, was used to assess the size of necrosis in patients with acute myocardial infarction. A close correlation between anterior left-ventricular myocardial infarction weight and congestive left-ventricular insufficiency has been demonstrated. No such correlation was demonstrated for inferior myocardial infarction.
