  • Patent number: 11925467
    Abstract: Various embodiments are described herein for a system and a method for assessing a risk of ventricular arrhythmias for a patient. For example, the method may comprise receiving ECG data obtained from the patient; analyzing the ECG data to detect abnormal QRS peaks; determining the risk of ventricular arrhythmias for the patient based on the detected abnormal QRS peaks; and providing an indication of the risk of ventricular arrhythmias for the patient. The system may be configured to perform this method.

  • Publication number: 20210169393
    Abstract: System, method and computer program product of assessing the likelihood of response to cardiac resynchronization therapy (CRT) for a patient. ECG data is obtained from the patient and is analyzed to detect abnormal QRS peaks. A likelihood of the patient responding to CRT is determined based on the number of abnormal QRS peaks detected. An indication of whether the patient is a candidate for CRT can be provided based on the determined likelihood of CRT response. This indication can be used to guide treatment for the patient.

  • Patent number: 10362956
    Abstract: Various embodiments are described herein for detecting a rotor at a location of a heart that experiences cardiac fibrillation. This generally involves obtaining a plurality of bipolar EGMs for a recording duration using a circular bipolar electrode array positioned at the location of the heart; detecting a dominant periodicity Cycle Length (CL) and identifying periodic activations for each bipolar EGM associated with the dominant periodicity CL; tracking the identified periodic activations across each bipolar EGM to define rotational activations and determining when a path taken by the tracked rotational activations corresponds to a rotational activation pattern of a rotor; and detecting the rotor when a number and completeness of the tracked rotational activations meet predefined rotor criteria.

  • Patent number: 10111598
    Abstract: Various embodiments are described herein for a system, method, and device for identifying focal source locations of electrophysiological activity in an organ. The system, method and device may also be used to guide catheter ablation of the organ. An electrogram signal can be obtained from a location in the organ, and it can be determined if the electrogram is periodic and, if so, the corresponding periodicity cycle length. A plurality of peaks associated with the cycle length can be identified. The location can be identified as a focal source location when the periodicity cycle length and the plurality of peaks have focal source characteristics. Methods are also described for identifying a direction of wave propagation and identifying multiple periodicities within an electrogram signal.

    Abstract: Various embodiments are described herein for a system, method, and device for identifying focal source locations of electrophysiological activity in an organ. The system, method and device may also be used to guide catheter ablation of the organ. An electro-gram signal can be obtained from a location in the organ, and it can be determined if the electrogram is periodic and, if so, the corresponding periodicity cycle length. A plurality of peaks associated with the cycle length can be identified. The location can be identified as a focal source location when the periodicity cycle length and the plurality of peaks have focal source characteristics.
