Example of the curves obtained with the pressure and area data points of the peak systolic pressure–end-systolic area relation, taken from 11 beats during the preoperative and postoperative inflow occlusions in patient 4 (control group).

3. Fig 2
Effect of treatment on perioperative difference (Δ) in slope and x intercept (Ao) of peak systolic pressure–end-systolic area relations in the overall group of patients. As shown by crowding of data points around the origin for effect of enflurane treatment, no significant change was measured by analysis of covariance in these patients, different from controls (p = 0.002).
