Abstract

Estimation of the basic metabolism in isolated preparation of the rat heart by means of extrapolation of partial regression of the total energy expenditure by the heart on cardiac effort index at constant oxygen supply of the preparation, revealed on the average 72% of the total energy expenditure by the working preparation. Estimation of the same parameter by means of measuring the heart oxygen consumption after heart arrest with potassium, at the same level of oxygen supply, revealed on the average 49% of the mean total energy expenditure by the working preparation. The level of oxygen supply appears to have a major significance for the estimation of the heart basic metabolism.
