%X Example of Classical LBBB contraction pattern. The features of a Classical LBBB contraction pattern are the following: 1) Peak shortening of the mid- and/or basal septum (light and dark red lines) within the initial 70% of the ejection phase (red arrow), 2) Initial stretch (blue arrow) of the mid- and/or basal lateral wall (light and dark green lines), and 3) late peak shortening after aortic valve closure (AVC - dotted line) of the mid- and/or basal lateral wall (yellow arrow). The apical segments are usually disregarded, when assessing the Classical LBBB contraction pattern, and therefore they have been omitted from this figure. The dots on each line mark the peak shortening of each segmen
