Figure 6 A box plot demonstrating the cross correlation between virtual and contact unipolar electrograms (top) and distance from the center of the array (bottom) with the ablation catheter at different anatomical sites in the left atrium during AF. The box represents the interquartile range and the thick line represents the median value. The left pulmonary veins and atrial appendage have the worse correlation, but they were also the furthest from the array. Ant = anterior wall of left atrium; LAA = left atrial appendage; LPV = left pulmonary veins; Post = posterior wall of left atrium; Roof = roof of the left atrium; RPV = right pulmonary veins.
