Systems, devices, components and methods for detecting the locations of sources of cardiac rhythm disorders in a patient's heart

A system for detecting a location of a source of at least one cardiac rhythm disorder in a patient's heart, comprising:

• an intracardiac catheter having a plurality of mapping electrodes;
• a navigation system configured to determine positions of the mapping electrodes when located within a chamber of the patient's heart;
• a computing device comprising at least one processor and at least one non-transitory computer readable medium configured to store instructions executable by the at least one processor for determining the source and location of the cardiac rhythm disorder in the patient's heart, the computing device being configured to:
• (a) receive electrogram signals acquired inside the chamber of the patient's heart using the plurality of mapping electrodes;
• (b) receive the determined positions of the mapping electrodes from the navigation system;
• (c) assign the determined positions of the mapping electrodes to their corresponding electrogram signals;
• (d) generate a two-dimensional (2D) spatial map of the electrode positions;
• (e) for selected discrete times over which the electrogram signals are being processed, process the electrogram signals to generate a plurality of three-dimensional electrogram surfaces corresponding at least partially to the 2D map, one surface being generated for each such time, and (e) process the plurality of three-dimensional electrogram surfaces through time to generate a velocity vector map corresponding at least partially to the 2D map, the velocity vector map being configured to reveal the location of the source of the at least one cardiac rhythm disorder;
• and
• a display operatively coupled to the computing device and including a display screen, the display configured to generate and display a graphical representation of the vector map on the display screen.
