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

A system to generate an aggregated stability map of one or more rotational sources associated with a heart rhythm disorder, the system comprising:

• a processing device;
• and
• a memory device storing a plurality of instructions that, when executed by the processing device, cause the processing device to perform operations comprising:
• accessing a plurality of rotational area profile maps generated based on sensed signals associated with the heart rhythm disorder, each of the rotational area profile maps being for a respective one of a plurality of analysis intervals, each of the rotational area profile maps including rotation intensity values for a plurality of locations associated with rotation of the one or more rotational sources;
• filtering the plurality of rotational area profile maps based at least on a selected filter number of highest rotation intensity values among a total number of rotation intensity values from corresponding locations of the plurality of rotational area profile maps, the selected filter number being selectable from a plurality of filter numbers;
• generating an aggregated stability map based on the plurality of rotational area profile maps as filtered, the aggregated stability map including a plurality of locations, each location of the plurality of locations in the aggregated stability map including a rotation intensity value that is based on the highest rotation intensity values as filtered from the corresponding locations of the plurality of rotational area profile maps;
• and
• presenting on a display the aggregated stability map as generated which amalgamates the rotation intensity values associated with the rotation of the one or more rotational sources over the plurality of analysis intervals, helping identification of and guidance to the one or more rotational sources in connection with diagnosis or treatment of the heart rhythm disorder.
