  1. Velocity variability shown in absolute values (cm/s) and percentage of the applied venc. Strain variability is reported in absolute values (%strain). Sc = Circumferential strain. N = 43x6 = 258. Values are mean ± 1.96*SD.
  2. *: Sc was also calculated from motion paths using only end-diastole as temporal origin, as described in [23], without our proposed extension of also including end-systole as temporal origin.
