Figure 3 The same patient as in Figure 2. One sample (yellow) is positioned at the base of the septum and another (green) is located in the posterior wall. In each point, strain rate (SR) analysis is carried out in a range of 10 mm. The first solid line (right panel) represents the onset of a negative SR in the septum (yellow line), indicating the onset of systolic shortening. The second solid line indicates cessation of systole, where the SR in the septum becomes positive. At the same time, a negative SR is observed in the posterior wall (green line), and this persists between the second and third lines, documenting shortening in early diastole (i.e., delayed longitudinal contraction).
