Median values of EIGDR indices ($\mathcal{R}$,${\mathcal{R}}^{\mathcal{A}}$and$\mathrm{\Delta }{\mathcal{R}}^{\mathcal{A}}$) computed over the six cliques considered for the PentaRay^® catheter, median ($V^b$) and maximum ($V^{b\text{-}m}$) bipolar amplitude computed over the five innermost electrode pairs along the splines of the catheter, at different mapping points, taken at fibrotic (F) and non-fibrotic (NF) areas, respectively. Median and interquartile range (IQR) were also performed among F and NF points, separately
