The total energy expenditure of the rat isolated heart and the external work of the preparation are positively correlated with the oxygen supply of the heart. A positive partial correlation was revealed between the total energy expenditure of the heart and the oxygen supply of the heart at constant external work of the heart which means that the heart efficiency coefficient decreases on an increase in the oxygen supply. By means of calculation of the partial regression of the heart total energy expenditure on external work at a constant oxygen supply, the "pure" efficiency coefficient of the heart (i. e. the ratio between an increment in the heart work and the corresponding increment of the total energy expenditure of the heart) was found to be about 41 per cent on the average.
大鼠离体心脏的总能量消耗及标本的外部功与心脏的氧供应呈正相关。在心脏外部功恒定的情况下，心脏总能量消耗与心脏氧供应之间呈现正偏相关，这意味着随着氧供应增加，心脏效率系数降低。通过计算在恒定氧供应条件下心脏总能量消耗相对于外部功的偏回归，发现心脏的“纯”效率系数（即心脏功的增量与心脏总能量消耗相应增量的比值）平均约为41%。
