Figure 2 Epicardial electrograms during right atrium pacing. A stained tissue slice is shown to orient sites A to L, where epicardial electrograms were directly measured and noninvasively reconstructed. The anterior, left, posterior and right labels are in reference to the heart oriented in the torso. The locations of the right ventricle (RV), left ventricle (LV) and infarct (light brown) are indicated. Measured electrograms are plotted in red and noninvasively reconstructed electrograms in blue.
