Figure 3. For EEPVI, the target sites are determined using multi-plane PV angiograms and local electrograms. In this case, at the posterior junction, the target electrogram is a large LA potential, and at the anterior junction the target electrogram is a complex potential consisting of LA component and spiky PV component superimposed (yellow arrow).
