Fig 1 The three cross-sections, plotted at 25%, 50%, and 75% of the left ventricle’s long axis. The area of these cross-sections was recorded continuously throughout a normal cardiac cycle. The Annals of Thoracic Surgery 2001 72, S1083-S1089DOI: (10.1016/S0003-4975(01)02938-1)

Fig 2 Typical electromechanical maps of infarcted myocardium at 3 days after induction of ischemia. Red indicates regions of abnormal electromechanical activity, whereas blue/purple designates a region in which function remains unhindered. (A) Bipolar electrogram amplitude, with red indicating amplitude <0.7 mV and purple designates amplitude >7 mV. (B) Local shortening, with red indicating abnormally contracting regions with values <4% and purple indicating normal contractile function >12%). Reconstructed maps are shown in a left anterior oblique projection, and the white head indicates the left ventricular base.
