    摘要： A timing circuit especially designed for use in implantable medical devices provides both a low frequency clock and a high frequency clock. The low frequency clock and high frequency clock are compared each time the oscillator producing the high frequency clock is enabled and the result of the comparison is used to retrim the high frequency oscillator to maintain a stable output frequency, even when subjected to drift. Additional circuitry is provided for signaling an oscillator fault in the event that an error signal resulting from the comparison of the low frequency clock with the high frequency clock exceeds a predetermined limit value. Digital trim values are stored for fast and controlled oscillator start-up.

    摘要： An implantable medical device may have a circuit failure mode. The disclosed circuit may have an integrated failure point designed to fail prior to those portions of the circuit. The integrated failure point may include a narrowed portion of a high voltage lead and a grounded lead having a narrow gap separating the grounded lead from the narrowed portion of the high voltage lead. During a high stress fault condition the narrowed portion of the high voltage lead acts as a fuse, forming a vaporized cloud of metal, which shorts current in the high voltage lead across the narrow gap to the grounded lead, thus protecting the remaining portion of the circuit from the high stress condition.

    摘要： An implantable cardiac rhythm management (CRM) device includes a sensing and detection circuit that senses at least one cardiac signal and detects cardiac electrical events from the sensed cardiac signal using a detection threshold that is adjusted based on a dynamic noise estimation. The sensed cardiac signal is filtered to produce a filtered cardiac signal having a signal frequency band and a noise signal having a noise frequency band. The noise frequency band is substantially different from the signal frequency band. A dynamic noise floor is produced based on the noise signal and used as the minimum value for the detection threshold. A cardiac electrical is detected when the amplitude of the filtered cardiac signal exceeds the detection threshold.
