摘要： An intra-body ultrasonic signal can be converted into a first electrical signal, a local oscillator signal can be generated in an implantable system. The first electrical signal and the local oscillator signal can be mixed in an implantable system, such as to generate a demodulated signal, processed, such as using a filter. The filtered, demodulated signal can be further processed, such as implantably determining a peak amplitude of the first portion of the demodulated signal received from the filter over a time interval, implantably generating a dynamic tracking threshold that starts at an amplitude proportional the first portion of the demodulated signal and exponentially decays over a time interval, and determining a noise floor in the absence of a received intra-body ultrasonic signal and implantably comparing the peak amplitude and the tracking threshold and generate the digital output based on the difference.

摘要： Systems and methods for adapting the performance of an acoustic communication link with an implantable medical device (IMD) are disclosed. An illustrative method includes initiating an acoustic link with the IMD, measuring an initial performance of the acoustic link, determining whether the initial performance of the acoustic link is adequate, adjusting an operating parameter related to the acoustic link in the event the initial performance of the acoustic link is inadequate, measuring a performance of the acoustic link in response to the adjusted operating parameter, and setting the operating parameter to a prior setting if the measured performance of the acoustic link does not improve in response to the adjusted operating parameter.

摘要： A plurality of separate indications of a scanner field can be received using a corresponding plurality of scanner field sensors of an implantable medical device (IMD). In an example, the IMD can be switched from a first therapy mode to a second therapy mode using one or more of the plurality of scanner field sensors, and from the second therapy mode back to the first therapy mode using each of the plurality of scanner field sensors. In certain examples, shock therapy can be terminated or inhibited using a detected proximity of the IMD to a magnetic resonance imaging (MRI) scanner, or antitachycardia pacing (ATP) can be terminated or inhibited using a detected active scan of the MRI scanner.

摘要： An implantable medical device includes a dual-use sensor such as a single accelerometer that senses an acceleration signal. A sensor processing circuit processes the acceleration signal to produce an activity level signal and a heart sound signal. The implantable medical device provides for rate responsive pacing in which at least one pacing parameter, such as the pacing interval, is dynamically adjusted based on the physical activity level. The implantable medical device also uses the heart sounds for pacing control purposes or transmits a heart sound signal to an external system for pacing control and/or diagnostic purposes.
