[Various rhythmologic precursors of terminal arrhythmia in patients with myocardial infarct].

The presence of near one hour ultradian cardiac rhythm was revealed on the ECG of 24 patients with acute myocardial infarction during 24-hour Holter monitoring. A classification of the phases of near one hour rhythm was developed according to the first coefficient value of autocorrelation of cardiac rhythm function. Special attention was attracted to the critical phase indicating high probability of the development of terminal arrhythmia and the threatening phase preceding it.

[Dynamics of the joint pains at night in rheumatoid arthritis and arthroses treated with Rengasil and piroxicam].

The effect of a novel nonsteroidal antiinflammatory drug Rengasil on pain at rest in rheumatoid arthritis and arthroses was studied in comparison with piroxicam and placebo.
