1. A method for an automated detection of sites of latest electrical activation of a human heart, comprising:
constructing a number of isopotential maps associated with an electrical potential distribution on a surface of the heart in respective times within a processing period occurring near an end of a ventricular or atrial depolarization;
processing the isopotential maps to identify regions of maximal positive electrical potential;
determining barycenters of the identified regions; and
localizing a site of latest heart electrical activation based on the determined barycenters,
wherein constructing the isopotential maps is performed in a period from 80% to 90% of a duration of a depolarization period.
