Difference: mean ± standard deviation of paired difference (manual measurement minus automated measurement). Probabilities (P) were obtained by paired sample t-test. For linear regression the automatically obtained values (y) were plotted as a function of the manual values (x) to calculate the fits and coefficients of determination (R²). EDV, end diastolic volume; EF, ejection fraction; ESV, end systolic volume; LVM, left ventricular mass; HEA, healthy; HFI, heart failure with ischemia; HFNI, heart failure with no ischemia; HYP, hypertrophy
