Velocity color maps for a radial, b longitudinal, and c tangential segmental LV motion from a healthy volunteer (top) and a PH patient (bottom). The maps represent motion of sequential LV segments (y-axis) throughout the cardiac cycle (x-axis). The wave color (blue or red) indicates direction of motion, with color intensity representing relative magnitude of the segmental velocity. There are segmental E wave abnormalities in all components of motion: a Radially: In health, E wave timing is uniform throughout LV segments. In early diastole in PH, the anterior segment tends to move outwards (Erad wave) first whilst the septum continues to move inwards. b Longitudinally: In health, peak anterolateral segment Elong waves are of significantly greater magnitude, compared with only a trend for greater lateral segment Elong waves in PH. c Tangentially: Reversal of E1 and E2 waves was observed in all patients
