Results of Bland-Altman analyses of CMR based measurements for stroke volume
Mean ± SD | Bias | Precision | 95% Limits of Agreement | Error (%) | |
PA Flow | 55.2 ± 13.1 | -4.2 | 11.48 | -18.3 to 26.8 | 42% |
Aorta Flow* | 51.40 ± 13.3 | -2.3. | 3.85 | -9.8 to 5.2 | 14% |
RV volumes | 59.5 ± 15.7 | -.75 | 11.49 | -23.3 to 21.8 | 39% |
LV volumes | 59.6 ± 16.2 | -0.8 | 4.87 | -10.4 to 8.8 | 16% |
NOTE. Values are ml, PA = Pulmonary artery, RV = right ventricle, LV = Left ventricle. *Aorta flow in nine patients.
