Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | The purpose of this study is to evaluate the conductibity of coronary vessels for the study of blood flow in the surface layer of the myoc ardium during warming up and cooling of the heart in conditions of cardiopulmonary bypass. Results. The numerical value of the quantitative criterion obtained is calculated by determining the difference in temperature between the blood and the myocardium, calculated as the difference between the geometric areas under the temperature distribution curves in the temperature field equation for the constant and the current fluxing temperature. The contouring method for determining the conductibity of coronary vessels allows to select areas on the surface of the myocardium, in which the change in temperature significantly lags behind the average temperature on the surface during warming or cooling of the heart, which indirectly allows evaluating the state of small coronary vessels in the myocardium. |
