Figure 3: Combined Fields of View from Mini- or Micro-electrode-embedded Catheters.

There are four possibilities of combined field of view with ME-embedded catheters. No signal on both, a sharp signal on both, a sharp signal on Abl but not ME and a sharp signal on ME but not ABL. First EGM shows nice fragmented bridging of the remaining gap on the pulmonary vein isolation circle. The second EGM is a far-field fragmented signal. The last EGM demonstrates an ideal fragmented NF LAVA signal. Abl d= distal ablation electrode; ABL dist= distal ablation electrode; ABL p = proximal ablation electrode; ABL prox = proximal ablation electrode; EGM = electrogram; LAVA = local abnormal voltage activity; ME = mini- or micro-electrode.
