(AVI) (429 KB) An example of color-coded radial strain from speckle-tracking in a normal control from the mid-ventricular short-axis view. Note mechanical activation indicated by the red-color coding of strain (% thickening) occurs uniformly among radial segments.
- Movie II
-
(AVI) (355 KB) An example of color-coded radial strain from speckle-tracking in a heart failure study patient with left bundle branch block from the mid-ventricular short-axis view. Note mechanical activation indicated by the red-color coding of strain (% thickening) begins in the anterior septum and propagates posteriorly in a clockwise fashion.
