Abstract
Based on the systemic symmetrical approach, experimentally determined parameters of action potential and contractile response of frog myocardial strip were analyzed prior to and after the administration of several physiologically active drugs (caffeine, neoepinephrine, nembutal, ouabain) into the perfusate. It was shown that the satisfactory functional state of preparation was characterized by an interrelation between parameters in the form of a harmonic proportion with relatively constant coefficient. When the functional state of subject is affected by a physiologically active substance, the interrelation between the parameters is considerably changed. Based on the analysis of the data of literature, it was found that the interrelation between temporary parameters of action potential in various structures from human heart has the form of a harmonic proportion with a constant coefficient close to the invariant of "Gold Wurf" proportion. The similarity is underlined of principles of cardiac function temporary arrangement at levels of cell, organ and organism.
