Abstract

Disclosed are various examples and embodiments of systems, devices, components and methods configured to detect a location of a source of at least one cardiac rhythm disorder in a patient's heart. In some embodiments, electrogram signals are acquired from inside a patient's heart, and subsequently normalized, adjusted and/or filtered, followed by generating a two-dimensional spatial map, grid or representation of the electrode positions, processing the amplitude-adjusted and filtered electrogram signals across the 2D representation to generate a plurality of three-dimensional electrogram surfaces, one surface being generated for each or selected discrete times, and processing the plurality of three-dimensional electrogram surfaces across the 2D map through time to generate a velocity vector map. The resulting velocity vector map is configured to reveal the location of the source of the at least one cardiac rhythm disorder, which may be, by way of example, an active rotor in a patient's myocardium and atrium.
