[A method of continuous registration of heat production of the heart].
A new method of continuous registration of the cardiac heat production was developed for the quantitative assessment of the levels of metabolic processes in cardiac hemodynamic reactions. The method is based on the technique of coronary arteries catheterization and extracorporeal perfusion, coronary sinus catheterization with a special catheter equipped with miniature-temperature transducer and a device designed for transformation of blood temperature values into the electrical signals. The data on the changes in cardiac heat production during cardiovascular adrenergic reactions and in conditions of acute myocardial ischemia have been obtained. It has been shown that changes in myocardial heat production depend significantly on the direction of shifts in the cardiac function and associated alterations in the level of myocardial metabolic processes.
