Abstract

Systems and methods are provided that can identify a mechanism of action of an arrhythmia in a chamber of the heart. A plurality of electrograms recorded by a plurality of electrodes contacting a wall of a chamber of the heart at a corresponding plurality of different locations within the chamber in response to an electrical perturbation can be received. An activation map of the chamber can be determined based on the plurality of electrograms. Based on the activation map, a location and a shape of a mechanism of action of the arrhythmia can be determined. A treatment plan can be developed based on a location and a size of the mechanism of action within the chamber. For example, the treatment plan can include guiding an ablation of the mechanism of action.
