| Table 1: Tissue Doppler velocities, strain and strain rate- normal RV value. The values in the table are shown as follows. For each age group the standard deviation (s) was taken to construct ranges of the mean ± 2s. Abbreviations: A`, peak late diastolic velocity, COV, coefficient of variation; CTDI, color tissue Doppler imaging, E`, peak early-diastolic velocity; NA, not available; PTDI, pulsed tissue Doppler imaging; S`, peak systolic velocity.
