in 13 excised , cross-circulated canine hearts , we studied the correlation between left ventricular oxygen consumption per beat ( mvo2 ) and the magnitude of a specific pressure-volume ( p-v ) area circumscribed by the end-systolic and end-diastolic p-v relationship curves and the systolic segment of the p-v trajectory of a left ventricular contraction .
