Rajasekhar V. Suribhotla has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Multiple templates for filtering of far field R-waves
    Patent number: 6810283
    Abstract: The invention presents techniques for processing an atrial electrogram. An atrial electrogram senses atrial events, but may also sense a ventricular event, causing a far field R-wave to be present in the atrial electrogram signal. A far field R-wave is an undesired artifact. The invention provides techniques for estimating the far field R-wave and subtracting the far field R-wave from the atrial electrogram signal.
    Type: Grant

    Date of Patent: October 26, 2004
    Assignee: Medtronic, Inc.
