ABSTRACT

In 22 patients who were in a resuscitative unit the authors analyzed variations in cardiac rhythm by using informative criteria. It was shown that varying severity of a patient's status was characterized by different values of the informative criterion chosen and obtained from an analysis of appropriate time cardiac interval sequence. The presented results suggest that in terms of the information theory, the analysis of cardiac rhythm is principally suitable for operative control of the functional state of the patient who is in an intensive care unit.
