[Effect of the use of lidocaine on patients with acute myocardial infarct].

In 411 patients with acute myocardial infarction (AMI) the effect of intravenous lidocaineeee administration was studied in a suboptimal dose - under 1,5 mg/min (to 1979) and in the optimal dose - over 1,5 mg/min, minimum 2 mg/min during the first 12 hours, with an average 24 h dose, 3,0 g in the course of 48 hours. The patients were grouped into three prognostic groups, depending on their initial assessment according to the coronaryprognostic index of M. R.

[Polarcardiographic diagnosis of an infarct of the anterior wall of the heart in its subacute and chronic stages].

One hundred and ten patients, with clinically confirmed acute myocardial infarction of the anterior wall in subacute and/or chronic stage were polarcardiographically examined. The polarcardiograms were recorded with e velocity of the record 100 mm/s by an original little analogue computer, designed at RIMT, Ministry of Public Health, connected to a 6-channel ECG apparatus, programmed for orthogonal Frank leads. The recorded curves of space magnitude (M), transversal magnitude (tm) and length were quantitatively analyzed for amplitudes and time intervals.

[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.
