    摘要: Systems and methods for cardiac contraction detection using information indicative of lead motion are described. In an example, an implantable medical device can include a receiver circuit configured to be electrically coupled to conductor comprising a portion of an implantable lead and be configured to obtain information indicative of a movement of the implantable lead due at least in part to a motion of a heart. The device can include a processor circuit configured to determine whether a cardiac mechanical contraction occurred during a specified interval included in the obtained information indicative of the movement of the implantable lead. The processor circuit can be configured to determine information about the cardiac mechanical contraction using the obtained information indicative of the movement of the implantable lead.

    摘要: Advanced patient management systems include a unit for collecting data from a device associated with a patient, and a host in communication with the unit, the host identifying a time for the device to update data on the device. The system can identify a time for the device to update data associated with the device by developing a histogram of the availability of the device for interrogation. The system can also optimize processing loads for the system by developing a histogram of the time at which the caregiver is most likely to access the system to review the collected and processed data. Methods for optimizing device data update and processing times are also included.

    摘要: An implantable medical device can establish one or more artificial conduction pathways during tachyarrhythmia. Withdrawal of the artificial conduction pathway may help self-terminate the tachyarrhythmia, or may pre-condition the tachyarrhythmia to be more favorable for receiving an anti-tachyarrhythmia therapy, such as anti-tachyarrhythmia pacing, defibrillation shock therapy, or cardioversion. This can help provide enhanced anti-tachyarrhythmia therapy.

    摘要: Cardiac monitoring and/or stimulation methods and systems provide monitoring, defibrillation and/or pacing therapies. A signal processor receives a plurality of composite signals associated with a plurality of sources, separates a signal using a source separation algorithm, and identifies a cardiac signal using a selected vector. The signal processor may iteratively separate signals from the plurality of composite signals until the cardiac signal is identified. The selected vector may be updated if desired or necessary. A method of signal separation involves detecting a plurality of composite signals at a plurality of locations, separating a signal using source separation, and selecting a vector that provides a cardiac signal. The separation may include a principal component analysis and/or an independent component analysis. Vectors may be selected and updated based on changes of position and/or orientation of implanted components and changes in patient parameters such as patient condition, cardiac signal-to-noise ratio, and disease progression.

    摘要: A nondefibrillating and nonfibrillation-inducing energy is delivered at a first internal thoracic location. A first resulting electrical signal is detected at a second internal thoracic location in or near a target region of a heart. A first defibrillation threshold is estimated using the nondefibrillating and nonfibrillation-inducing energy, the first resulting electrical signal, and a target electric field strength. The defibrillation threshold represents an energy that when delivered at the first internal thoracic location creates an electric field strength in the target region of the heart that meets or exceeds the target electric field strength.

    摘要: This document describes, among other things, a body having at least one acoustically detectable property that changes in response to a change in a physiological condition, such as ischemia. The body is positioned with respect to a desired tissue region. At least one acoustic transducer is used to acoustically detect a change in physical property. In one example, the body is pH sensitive and/or ion selective. A shape or dimension of the body changes in response to pH and/or ionic concentration changes resulting from a change in an ischemia state. An indication of the physiological condition is provided to a user.
