Figure 3 Activation Map and Bipolar Voltage Map of the LA During Sinus Rhythm in a Patient Who Underwent the Randomized Ablation Strategy
(A) Earliest activation is 30 ms after P-wave onset in the septum (red). Latest activation is after QRS complex in the left atrial (LA) appendage (dark blue), at 325 ms after P-wave onset. (B) Scar or low-voltage area is observed in the anterior LA and septum. Tissue damage in these regions seems to be associated with intra-atrial conduction abnormality. Purple represents bipolar voltages of  0.5 mV.
