Bland-Altman analysis for inter-observer variability and inter-observer variability of all three-dimensional (3D) speckle-tracking imaging measures. (a) Inter-variability of conventional 3D echocardiographic parameters; (b) Intra-variability of conventional 3D echocardiographic parameters; (c) Inter-variability of segmental peak strain and characteristics of strain-volume loops; (d) Intra-variability of segmental peak strain and characteristics of strain-volume loops. LVEDV, left ventricular end-diastolic volume; LVEF, left ventricular ejection fraction; LVESV, left ventricular end-systolic volume; GCS, global circumferential strain; GLS, global longitudinal strain; PS, principal strain; SDI, strain delay index; Tmsv-SD%, standard deviation of time to minimum systolic volume corrected by R-R interval; TpPS-SD%, standard deviation of time to peak principal strain corrected by R-R interval
