  • Cardiac signal T-wave detection
    Patent number: 11918815
    Abstract: An example device for detecting one or more parameters of a cardiac signal is disclosed herein. The device includes one or more electrodes and sensing circuitry configured to sense a cardiac signal via the one or more electrodes. The device further includes processing circuitry configured to determine a representative signal based on the cardiac signal, the representative signal having a single polarity, and determine an end of a T-wave of the cardiac signal based on an area under the representative signal.
    Type: Grant
    Filed: May 3, 2022
    Date of Patent: March 5, 2024
    Assignees: Medtronic, Inc., UMC Utrecht Holding B.V.
    Inventors: Alfonso Aranda Hernandez, Berthold Stegemann, Marc A. Vos, David J. Sprenkeler
