Figure 3 Electroanatomic bipolar voltage and activation map in Patient #3 performed during premature beats. The activation map demonstrates the centrifugal activation from the border-zone of the scar. The voltage map (right panel) delineates the region of scar border-zone. Note that the premature beats originating from the Purkinje network are in this border-zone, where successful ablation was performed (brown tags). Purple tags represents sites recording Purkinje potentials, and white tags represent fractionated complex electrograms.
