Figure 5 Bipolar Voltage Map of the LA in a Patient Who Underwent the Specific Ablation Strategy

(A) Anteroposterior projection; (B) posteroanterior projection. Scar tissue is limited in the pulmonary vein region, accounting for 17% of the left atrial (LA) surface areas. Low-voltage tissue is present in the anterior LA and LA roof, accounting for 5% of the LA surface areas. Purple represents bipolar voltages of 0.5 mV.
