Patent number: 11975204Abstract: In some examples, a system can be used for delivering cardiac resynchronization therapy (CRT). The system may include a pacing device configured to be implanted within a patient. The pacing device can include a plurality of electrodes, signal generation circuitry configured to deliver ventricular pacing via the plurality of electrodes, and a sensor configured to produce a signal that indicates mechanical activity of the heart. Processing circuitry can be configured to identify one or more features of a cardiac contraction within the signal, and determine whether the contraction was a fusion beat based on the one or more features.Type: GrantFiled: September 20, 2021Date of Patent: May 7, 2024Assignee: Medtronic, Inc.Inventors: Robert W. Stadler, Richard Cornelussen, Berthold Stegemann

Publication number: 20240049968Abstract: In some examples, determining a heart failure status using a medical device comprising one or more sensors includes determining a first value of a heart beat variability metric of a patient while an activity state of a patient satisfies an inactivity criterion based on a signal received from the one or more sensors, and determining, within a predetermined period of time after further determining that the activity state of the patient no longer satisfies the inactivity criterion, a second value of the heart beat variability metric while the activity state of the patient no longer satisfies the inactivity criterion based on the signal. A difference between the first value of the heart beat variability metric and the second value of the heart beat variability metric may be determined and the heart failure status of the patient may be determined based on the difference.Type: ApplicationFiled: October 23, 2023Publication date: February 15, 2024Inventors: Alfonso Aranda Hernandez, Richard Cornelussen, Mirko de Melis, Richard Sutton, Berthold Stegemann
