Assignee:

Medtronic, Inc. - Minneapolis MN

International Classification:

A61B 5/04

US Classification:

600515, 600508, 600509

Abstract:

An implantable medical device and associated method monitor a physiological signal for sensing physiological events and detecting a physiological condition in response to the sensed physiological events. The device senses a first event from the physiological signal, senses a noise signal in the physiological signal and senses a next event from the physiological signal wherein the first event and the next event define a signal interval. The signal interval is declared as a noisy interval in response to the sensed noise signal.

US Classification:

607 18, 607 5, 607 9, 607 14

Abstract:

A method of detecting a cardiac event in a medical device that includes sensing cardiac signals from a plurality of electrodes forming a first sensing vector and a second sensing vector, determining whether the first sensing vector and the second sensing vector is corrupted by noise, and determining, in response to one of the first sensing vector and the second sensing vector being corrupted by noise, whether the other of the first sensing vector and the second sensing vector is one of a first cardiac event and a second cardiac event different from the first cardiac event.

International Classification:

A61B 5/0452

US Classification:

600509, 600519

Abstract:

A method and apparatus for determining oversensing of cardiac signals that includes a housing containing electronic circuitry, an electrode coupled to the electronic circuitry to sense cardiac signals, and a processor, positioned within the housing, to determine an oversensing characteristic associated with the cardiac signals sensed over a predetermined sensing window, and to identify oversensing in response to the determined oversensing characteristic.

International Classification:

A61B 5/0402

US Classification:

600512, 607 9

Abstract:

A method of detecting a cardiac event in a medical device that includes sensing cardiac signals from a plurality of electrodes forming a first sensing vector and a second sensing vector, and determining first heart rate estimates associated with cardiac signals sensed from the first sensing vector and cardiac signals sensed from the second sensing vector in response to a metric of heart rate associated with the sensed cardiac signals. Second heart rate estimates associated with the first sensing vector and with the second sensing vector are generated in response to the determined first heart rate estimates, and a determination is made as to whether both of the second heart rate estimates are greater than a predetermined heart rate threshold.

US Classification:

600509

Abstract:

A method and apparatus for determining oversensing in a medical device that includes sensing cardiac signals, determining an oversensing characteristic associated with cardiac signals sensed during a predetermined sensing window, identifying oversensing in response to the oversensing characteristic, determining, in response to oversensing being identified, an adjusting characteristic associated with cardiac signals sensed during the predetermined sensing window, and updating a sensing parameter in response to the determined adjusting characteristic.

International Classification:

A61N 1/00

US Classification:

607 2

Abstract:

Electrical crosstalk between two implantable medical devices or two different therapy modules of a common implantable medical device may be evaluated, and, in some examples, mitigated. In some examples, one of the implantable medical devices or therapy modules delivers electrical stimulation to a nonmyocardial tissue site or a nonvascular cardiac tissue site, and the other implantable medical device or therapy module delivers cardiac rhythm management therapy to a heart of the patient.
