Patents by Inventor Harold Toby Markowitz

Harold Toby Markowitz 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).

  • Identification and treatment of junctional rhythms
    Patent number: 8204593
    Abstract: An implantable medical device and associated method provide atrial pacing and measure intervals between atrial pacing pulses and subsequently sensed ventricular events. A decreasing trend in the intervals indicative of a pre-junctional rhythm is detected. The atrial pacing pulse is delivered at a shortened atrial pacing pulse interval in response to detecting the decreasing trend to reduce the likelihood of a junctional rhythm.
    Type: Grant

  • Methods and apparatus for detection and treatment of syncope
    Patent number: 6895275
    Abstract: The present invention relates to methods and apparatus for detection and treatment of syncope in an implantable medical device, and particularly to detection of syncope as a function of a predetermined increase in one or more respiration parameter and drop in heart rate and optionally delivering a pacing therapy in response thereto. The onset of a syncopal episode is declared when the patient's respiration rate and/or tidal volume and/or minute ventilation increases by a predetermined increment or threshold and a heart rate drops below a threshold heart rate drop. The threshold heart rate drop is preferably established as a function of the change in the respiration parameter.
