  1. Mean ± SEM. n = 7. LVSPmax and LVEDP = left ventricular peak systolic and –end-diastolic pressure; dP/dtmax and dP/dtmin = peak positive and peak negative first derivatives of left ventricular pressure; MAP = mean aortic pressure; *denotes significant difference from baseline value by paired sample t-test.
