  • Publication number: 20230075266
    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.

  • Publication number: 20230005625
    Abstract: A non-invasive method for cardiac arrhythmia risk stratification may include identifying, based at least on an electrical recording of a patient, a cardiac depolarization simulation and a cardiac repolarization simulation corresponding to an electrical recording of a patient. One or more regions of increased spatial repolarization gradient in which a first area of a myocardium of the patient exhibits a first repolarization rate that differs from a second repolarization rate of a second area of the myocardium by an amount then divided by the spatial distance between the two regions, by a threshold value may be determined based on the cardiac depolarization simulation and the cardiac repolarization simulation. A risk of cardiac arrhythmia for the patient may be determined based a magnitude of the increased spatial repolarization gradient. Moreover, a treatment plan for the patient may be determined based on the magnitude and/or location of the increased spatial repolarization gradient.

  • Publication number: 20220061732
    Abstract: Methods to enhance the computational localization of cardiac arrhythmia sources are provided. A method may include receiving, from a first user, clinical data associated with a clinical case. The clinical data may include a patient anatomic information, diagnostic and/or treatment modalities, treatment parameters, treatment outcome, and medical literature. The clinical case may be indexed based on a first plurality of characteristics associated with the clinical data. The indexing may include associating at least a portion of the clinical data with a computational simulation of cardiac arrhythmia having a second plurality of characteristics matching the first plurality of characteristics. At least a portion of the clinical data associated with the indexed case may be provided to a second user in response to a query from the user. Related systems and articles of manufacture are also provided.

  • Patent number: 11189092
    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.
