Figure 1

Shortening and stretching patterns in a patient with LBBB (left) and a normal individual (right) represented by a series of colour-coded bulls-eyes representing deformation-rate at 25 time points throughout the entire cardiac cycle for each of the 36 segments. Yellow = shortening, blue = stretching, green = no deformation/diastasis. AS = anteroseptum, ANT = anterior, LAT = lateral, POST = posterior, INF = inferior, SEPT = septum. In the normal individual (right), throughout most of the cardiac cycle all segments deform in phase (indicated by the same colour in all segments per frame). In LBBB (left) at many time points simultaneously occurring back-and-forth shortening (yellow) and stretching (blue) between septal regions and ventricular free wall can be appreciated.
