Figure 6 Isochronal maps demonstrating transmural scroll waves during VF from the right ventricle of heart no. 5. Times of activation are colored-coded according to the color bar above the panels. The numbers in the electrode arrays indicate the location and the numbers of the bipolar recording electrodes. From epicardium, subepicardium, subendocardium to endocardium (panels A to D), there were only small differences in the transmural distribution of activation patterns. The filament of this scroll wave (line connecting white circles near channels 217, 218, 219 and 220) was perpendicular to the surface of the ventricular wall. The white arrow in each panel indicates the rotating direction of the scroll wave.
