Figure 2

Shortening and stretching patterns in a patient with LBBB (left) and a normal individual (right) represented by a two-dimensional M-mode map representation of the same data as in figure 1: the temporal information can now be continuously plotted over time (left to right within each plot). Vertical lines represent event timing markers. Spatial representation is less optimal: each of the 6 walls is plotted separately (from top to bottom) with each level plotted from base (top) to apex (bottom) within the separate plots. As in figure 1, shortening and stretching are markedly inhomogeneous in LBBB (left) compared to NL (right).
