The analytical review examines the possibilities of research methods available for a wide clinical practice in the diagnosis of the phenomenon of myocardial stunning. Based on the definition of the phenomenon of myocardial stunning itself, its diagnosis should include: 1) identification of signs of myocardial ischemia with further reperfusion; 2) determination of a clinically significant decrease in cardiac performance, due precisely to the insufficiency of the myocardial inotropic function. In accordance with the content of modern authoritative guidelines created by international groups of experts, the most characteristic and reliable electrocardiographic signs of myocardial ischemia, echocardiographic signs of a decrease in contracti-lity of some myocardial segments and cardiac muscle in general were systematized. Taking into account all the advantages and disadvantages, the characteristics of the most common instrumental methods for evaluating heart performance are given, which are the basis of hemodynamic monitoring. Electrocardiographic diagnosis with echocardiographic monitoring is recognized as the method for detecting myocardial ischemia, which is most accessible for clinical use and most safe for critically ill patients. Objective assessment of the state of contractile function of some myocardial segments is possible with the use of numerous methods of echocardiography. At present, methods of 3D-sonographic diagnosis are rapidly developing. However, unified recommendations for their use have not been developed yet. Modern methods of hemodynamic monitoring, such as thermodilution, electrical method for determining biological impedance, photoplethysmography, are widely used to reveal the presence of a global reduction in cardiac performance.
