Figure 5 Epicardial potential maps during epicardial breakthrough. Potentials are displayed as color-coded maps. In each panel, measured potentials are on the left, and noninvasively reconstructed potentials are on the right. (A) Potentials corresponding to right atrium (RA) pacing (simulated sinus rhythm). The numbers mark the locations of the three epicardial breakthroughs. (B to G) Potentials corresponding to ventricular tachycardia (VT) cycles 1, 2, 3, 5, 8 and 9, respectively. *Locations of epicardial breakthroughs for each VT cycle. The distances between the measured and reconstructed breakthrough sites ( d) are provided.
