Described embodiments include a method that includesconstructing a computerized electroanatomical model of aportion of a heart, the model including a mesh, whichapproximates the portion of the heart, and a plurality ofpoints, at different respective locations on the mesh, havingrespective associated local activation times (LATs) that wereascertained from electrocardiographic signals acquired from theportion. The method further includes constructing a graph thatinterconnects the points and, based on the respective locationsand LATs of the points, identifying, from a plurality ofpathways, through the graph, from a first one .of the pointshaving a lowest one of the LATs to a second one of the pointshaving a highest one of the LATs, both a shortest pathway and alongest pathway. Themethod further includes displaying themesh, with the identified shortest pathway and longest pathwaysuperimposed over the mesh. Otherembodiments are alsodescribed.
