Ts-max, maximal difference in time to peak myocardial systolic velocity between any 2 of 12 LV segments; Ts-sd, standard deviation of time to peak myocardial systolic velocity of all 12 LV segments; Ts-sl, difference in time to peak myocardial velocity between septal and lateral LV walls; Tε-sl, difference in time to peak strain between septal and lateral LV walls.
Values are mean (±SD) and median (10–90% percentiles).
Significance of the sex difference: P ≤ 0.05.
