  • Publication number: 20260127743
    Abstract: A method may include identifying a simulated three-dimensional representation corresponding to an internal anatomy of a subject based on a match between a computed two-dimensional image corresponding to the simulated three-dimensional representation and a two-dimensional image depicting the internal anatomy of the subject. Simulations of the electrical activities measured by a recording device with standard lead placement and nonstandard lead placement may be computed based on the simulated three-dimensional representation. A clinical electrogram and/or a clinical vectorgram for the subject may be corrected based on a difference between the simulations of electrical activities to account for deviations arising from patient-specific lead placement as well as variations in subject anatomy and pathophysiology.

  • Patent number: 12543996
    Abstract: A method for localizing the source of an arrhythmia within a heart wall is disclosed. The method involves accessing an indication of the source location of the arrhythmia within the endocardium. A normal vector is generated that is normal to the endocardium at the source location in the direction of the epicardium layer. An activation vector indicating the direction of electrical force of the heart during an initial stage of depolarization is determined. The depth angle between the normal vector and the activation vector is determined, and the depth of the source location within the heart wall is indicated based on a depth angle.

  • Publication number: 20250378642
    Abstract: A system for computational localization of fibrillation sources is provided. In some implementations, the system performs operations comprising generating a representation of electrical activation of a patient's heart and comparing, based on correlation, the generated representation against one or more stored representations of hearts to identify at least one matched representation of a heart. The operations can further comprise generating, based on the at least one matched representation, a computational model for the patient's heart, wherein the computational model includes an illustration of one or more fibrillation sources in the patient's heart. Additionally, the operations can comprise displaying, via a user interface, at least a portion of the computational model. Related systems, methods, and articles of manufacture are also described.
