↵1-150 Difference by paired t test between the observed and predicted values.
↵1-151 Normal ranges: LVIDd 88–112%, LVIDs 82–118%, IVSd 82–118%, LVPWd 84–116%, AO 82–118%, and LAIDs 82–118%.35
↵1-152 LVEF and FS are independent of both body weight and age.35
AO, aortic root internal diameter; FS, fractional shortening; IVSd, interventricular septal wall thickness, end diastole; LAIDs, left atrial internal dimension, end systole; LVEF, left ventricular ejection fraction; LVIDd, left ventricular internal dimension, end diastole; LVIDs, left ventricular internal dimension, end systole; LVPWd, posterior left ventricular wall thickness, end diastole; ND, not determined.
