ABSTRACT
For a change, here is a simple numerical problem. 2.17 The pressure-volume loop of a human left ventricle had end-systolic and end-diastolic
volumes of 42 and 120 ml, respectively, the mean diastolic and mean systolic pressures were 8 and 88 mmHg, respectively, and aortic pressure was 119/79 mmHg. a. What was the subject’s stroke volume? b. How much did systole raise the mean left ventricular pressure? c. What, approximately, was the subject’s stroke work? d. What was the arterial pulse pressure?
