Figure 1: (A) Patient with antero-apical aneurysm (LAD infarct) with LV colored by HD at the instant of peak diastolic filling with regional P2PD history lines plotted showing a distinct (longer) history of contraction (blue) in viable LV regions (red, during diastolic filling). (B) HF patient and normal LVs compared at peak ejection (systole) and peak filling (diastole) instants, indicating that normal LV contraction showed uniformly blue (contraction) and red (expansion) whereas patient LVs had large akinetic (green) territories.
