System and method to define an aggregated stability map of a rotational source over a plurality of time intervals associated with a biological rhythm disorder

Abstract

Provided are a system and method of generating an aggregated stability map of one or more rotational sources associated with a heart rhythm disorder. In accordance therewith, a plurality of rotational area profile maps is accessed for a plurality of analysis intervals. Each of the profile maps includes rotation intensity values for a plurality of locations associated with rotation of the one or more rotational sources. An aggregated stability map is generated based on the profile maps, wherein the stability map includes a plurality of locations. Each location includes a rotation intensity value based at least on a filter number of highest rotation intensity values from corresponding locations of the profile maps, the filter number being automatically determined from a plurality of filter numbers such that the plurality of profile maps as filtered includes a predetermined number of rotation intensity values in excess of a threshold intensity value.
