Figure 3 Auto EF Versus Manual Biplane Simpson’s Rule Volumes
Scatter plots with linear regression (left) and Bland-Altman (right) analyses of assessment of left ventricular end-diastolic (top) and end-systolic (bottom) volumes by Auto EF versus manual tracings using Simpson’s rule, demonstrating a close correlation with a tendency for slight underestimation of volume by Auto EF.
