Figure 1

Diagram in 3D showing the relative position in a virtual left ventricle of the three regions that were quantified using the centreline method. Definition of segments was based on a visual wall motion score using a 17-segment model and a 5-point scoring system with 0: normal wall motion, 1: mild hypokinesia, 2: severe hypokinesia, 3: akinesia, and 4: dyskinesia. Myocardial segments with a visual wall motion score from 1 to 4 were considered as dysfunctional segments (grey). The myocardial segments next to these dysfunctional segments in 3-dimensions, were considered as adjacent segments (dashed). The remaining myocardial segments were considered as remote tissue (white).
