The NF algorithm may enable rapid high-density activation mapping of VT circuits in the near field of the mapped surface. Integrated assessment and combined analysis of near and far field EGMs could support characterisation of 3-dimensional VT circuits with intramural segments. For scar-related substrate mapping, PF as a stand-alone EGM feature did not enable the differentiation of functionally critical sites of the dominant VT from low voltage bystander sites in this cohort.
