Figure 4 Tissue synchronization imaging, four-chamber view. (Left) The color represents timing: green = normal timing; red = severe delay. Color-guided visual identification of the site of latest activation facilitates sample-placement to derive the tissue Doppler imaging (TDI) velocity tracings. In this patient, the earliest activation (green) is in the lateral wall, and the latest activation is in the lateral wall (red); the TDI velocity tracings (right) confirm the delay between the septum and lateral wall.
