[Polarcardiographic diagnosis of posterior wall myocardial infarct in the subacute and chronic stages].

One hundred and thirty patients with clinically confirmed myocardial infarction of the left ventricle posterior wall were polarcardiographically and electrocardiographically examined. Polarcardiograph was constructed at the RIMT, Ministry of Public Health. The spatial, sagittal size and gamma length were quantitatively analyzed. The results are compared with the PCG analysis of 114 healthy subjects. PCG is with 18.4 per cent more sensitive as compared with the single ECG with 12 leads, in making the diagnosis of myocardial infarction of the posterior wall in subacute and/or chronic stage.
