Correlation and bias for the atrial contraction, automatic tracking compared to manual measurements. Scatter plot of the atrial contraction in % of the AVPD in end systole (left panel) and the corresponding modified Bland-Altman plot (right panel) for the automatic tracking against manual measurements in n = 20 subjects. Top row shows results for the left ventricle and the bottom row shows the results for the right ventricle. The identity line is shown as a solid line in the scatter plots, and linear regression as a dashed line. In the modified Bland-Altman plots the mean bias is shown as a solid line with limits of agreement (±2SD) as dashed lines. Correlation R value was 0.49 for the left ventricle, and 0.39 for the right ventricle. For the left ventricle, mean bias was −1.5% with limits of agreement between −20.9 and 17.9%. For the right ventricle, mean bias was 3.3% with limits of agreement between −14.3 and 20.9%
