Detection of exit sites. A: Examples of distance fields computed from pacing sites located at the apex (upper panel) and base (bottom panel). B: Split surfaces detected within the isthmuses at different distances $d$ from the pacing sites. Isosurfaces in green are associated with the distal mouths, i.e., exit sites, of the isthmuses. 3D surfaces are shown as lines on the LV epicardium for visualization purposes.
