Limits of agreement (LoA) centered on the mean difference (in milliliters and millijoule) and expressed as a percentage of the mean volume or total kinetic energy. 95% confidence intervals are given for the limits of agreement and the mean differences. LV = left ventricle; LA = left atrium; RV = right ventricle; RA = right atrium; Ao = aorta; PA = pulmonary artery; EDV, end‐diastolic volume; ESV, end‐systolic volume; tot KE, total kinetic energy.
