a Bland-Altman plot for end diastolic volumes showing differences between the measurements at the various breathing phases (Inspiratory vs. expiratory: bias = 1.0 mL ± 6.0 mL, inspiratory vs. free breathing: bias = −0.3 mL ± 7.9 mL and expiratory vs. free breathing: bias = 0.8 mL ± 8.0 mL). b Bland-Altman plot for end systolic volumes showing differences between the measurements at the various breathing phases (Inspiratory vs. expiratory: bias = −1.2 mL ± 5.6 mL, inspiratory vs. free breathing: bias = −0.7 mL ± 4.5 mL and expiratory vs. free breathing: bias = 0.5 mL ± 5.0 mL)
