Figure 5 Recordings from a single experiment during left anterior descending artery occlusion. (Upper panels) Left ventricular (LV) short-axis shortening at mid-ventricular level (left) and apical level (right). (Middle panels) Long-axis strain in the septum (left) and lateral wall (right). (Lower panels) LV pressure (LVP) for timing. Reduced short-axis systolic shortening and lateral wall strain indicate ischemic dysfunction. Dashed line = sonomicrometry, solid line = speckle tracking echocardiography.
