the lambs were studied 3 d later by making intermittent measurements of aortic and coronary sinus blood oxygen saturations and hb concentrations , left ventricular myocardial blood flow , cardiac output , heart rate , left atrial and aortic blood pressures , the maximal first derivative of left ventricular pressure , aortic and coronary sinus blood oxygen contents , the arteriovenous difference of oxygen across the left ventricular myocardium , myocardial oxygen consumption , and external cardiac work ( aortic mean blood pressure times cardiac output ) .
