    摘要: The invention is directed to an implantable medical device that stimulates a nerve associated with respiration. The nerve may, for example be a phrenic nerve, and the stimulation may cause a diaphragm of the patient to contract. The implantable medical device receives a signal that indicates a need for increased cardiac output and stimulates the nerve in response to the signal. The implantable medical device may receive such a signal by, for example, detecting a ventricular tachyarrhythmia, sensing a pressure that indicates a need for increased cardiac output, or receiving a signal from a patient via a patient activator. Stimulation of the nerve may increase cardiac output of a beating or defibrillating heart

    摘要: A method and apparatus for actively determining a coupling interval corresponding to a cardiac vulnerable zone associated with a therapy of an implantable medical device that includes a timing and control unit delivering, via electrodes of a plurality of electrodes, a first pulse train and a first pulse signal at a predetermined time interval from delivery of a last pulse of the first pulse train. A sensor determines an evoked response corresponding to the first pulse signal, and a microprocessor compares the evoked response to a prior determined evoked response and sets the coupling interval equal to the predetermined time interval in response to the latency of the evoked response having increased by a first predetermined amount, and reduces the predetermined time interval by a second predetermined amount in response to the latency of the evoked response not having increased by the first predetermined amount.

    摘要: The present invention outlines structures and methods for delivering a controllable amount of energy to a patient by automatically compensating for the load impedance detected by an implantable-cardioverter defibrillator (ICD). The invention employs high speed, switching power converter technology for the efficient generation of high energy, arbitrary waveforms. Unlike a linear amplifier, switching power converters deliver high-energy waveforms with an efficiency that is independent of the size and amplitude of the desired waveform. An ICD that uses a switching power converter to deliver the desired energy to the patient stores the energy to be delivered in a storage capacitor. The converter then transforms this energy into an arbitrarily shaped output voltage-controlled or current-controlled waveform by switching the storage capacitor in and out of the output circuit at a high rate of speed. Preferably, the waveform comprises a ramp-type waveform.

    摘要: An example system may include at least one pressure sensor configured to measure a cardiovascular pressure signal and another medical device configured to measure an electrical depolarization signal of the heart. The system determines a plurality of cardiovascular pressure metrics based on the measured cardiovascular pressure signal, including at least one cardiovascular pressure metric indicative of a timing of at least one cardiac pulse. The system also determines a metric indicative of a timing of at least one heart depolarization within the measured electrical depolarization signal. The system compares the timing of the at least one cardiac pulse to the timing of the at least one depolarization, and determines whether to discard the plurality of cardiovascular pressure metrics based on whether the timings substantially agree.

    摘要: A method and apparatus for validating cardiac pacing pulse train preceding a T- shock. Validation of the pacing pulse train includes verifying capture of at least the last pacing pulse of the pulse train and verifying that intrinsic ventricular events are not sensed during a pacing train interval that includes at least the interval between the last pacing pulse and a scheduled T-shock delivery. Capture verification may include sensing an event during an ER (evoced response) sensing window, morphological analysis of a sensed event, and analysis of the temporal relationship between sensed events occurring on different EGM sources. The scheduled T-shock is delivered in response to a valid pacing pulse train. A response to an invalid pacing pulse train may include any of an invalid pacing train notification, withholding a scheduled T-shock, extension of the pacing train, repeating the pacing train, or adjusting the pacing pulse train parameters.
