Figure 2. Representative example of the rapid time course of ablationinduced attenuation of B-EGM and U-EGM amplitude and shift to monophasic R-wave in U-EGM during an application at the anteroinferior quadrant of the right circle (45s application reaching an ablation index of 574, impedance drop of 25Ω, CF of 11g, average power 35W).
