Patent number: 11413468Abstract: Signal analysis in an implanted cardiac monitoring and treatment device such as an implantable cardioverter defibrillator. In some examples, detected events are analyzed to identify changes in detected event amplitudes. When detected event amplitudes are dissimilar from one another, a first set of detection parameters may be invoked, and, when detected event amplitudes are similar to one another, a second set of detection parameters may be invoked. Additional examples determine whether the calculated heart rate is “high” or “low,” and then may select a third set of detection parameters for use when the calculated heart rate is high.Type: GrantFiled: September 29, 2017Date of Patent: August 16, 2022Assignee: CAMERON HEALTH, INC.Inventors: Venugopal Allavatam, Surekha Palreddy, Rick Sanghera, Jay A.

Patent number: 10974058Abstract: Methods, systems, and devices for signal analysis in an implanted cardiac monitoring and treatment device such as an implantable cardioverter defibrillator. In illustrative examples, captured data including detected events is analyzed to identify likely overdetection of cardiac events. In some illustrative examples, when overdetection is identified, data may be modified to correct for overdetection, to reduce the impact of overdetection, or to ignore overdetected data. New methods for organizing the use of morphology and rate analysis in an overall architecture for rhythm classification and cardiac signal analysis are also discussed.Type: GrantFiled: January 23, 2019Date of Patent: April 13, 2021Assignee: CAMERON HEALTH, INC.Inventors: Venugopal Allavatam, Surekha Palreddy, Rick Sanghera, Jay A.

Data manipulation following delivery of a cardiac stimulus in an implantable cardiac stimulus device
Patent number: 9242112Abstract: Methods of cardiac rhythm analysis in an implantable cardiac stimulus device, and devices configured for such methods. In an illustrative embodiment, certain data relating to cardiac event rate or amplitude is modified following delivery of a cardiac stimulus. In another embodiment, cardiac rhythm analysis is performed using one of plural states, with the plural states using different criteria, such as a detection threshold, to detect cardiac events in a sensed signal. Following delivery of a cardiac stimulus, data is manipulated to force the analysis into one of the states, where stimulus is delivered, in the illustrative embodiment, only after a different state is invoked. Implantable devices incorporating operational circuitry for performing such methods are also included in other illustrative embodiments.Type: GrantFiled: February 20, 2014Date of Patent: January 26, 2016Assignee: CAMERON HEALTH, INC.Inventors: Surekha Palreddy, Venugopal Allavatam -
