FIELD: medicine. SUBSTANCE: method involves applying continuous cardiointervalogram monitoring. Relative entropy of cardiac cycle duration and its phase trajectory in building and continuously incremental multidimensional space. The results are transformed into two-dimensional image. Dynamic chaos degree criterion is determined that is based on density of filling selected area of the above mentioned phase space with entropy measurements. Amplitude oscillations exceeding 20% threshold on criterion curve considered as function of time are thought to be a sign of acute homeostasis system regulation disorder accompanying myocardial ischemia development. EFFECT: enhanced effectiveness in early recognition of metabolic myocardial disorders. 1 dwg
