Anna Björkenheim et al. JACEP 2017;j.jacep.2017.04.003 Scatterplot Comparing Changes in AF6 Sum Score and European Heart Rhythm Association Class Before and After Ablation (A) 6 months (r = 0.31, r2 = 0.10, p = 0.02), (B) 12 months (r = 0.32, r2 = 0.10, p = 0.03), and (C) 24 months (r = 0.22, r2 = 0.05, p = 0.12) after ablation. Negative values indicate improvement and positive values deterioration. Patients in the lower left quadrant show improvement and in the upper right quadrant worsening in both AF6 score and European Heart Rhythm Association (EHRA) class, while patients with discordant results are found in the upper left and lower right quadrants.
