    摘要： Techniques for minimizing interference between the first and second medical devices or between the different therapy modules of a common medical device are described herein. In some examples, a medical device may include shunt-current mitigation circuitry and/or at least one clamping structure that helps minimize or even eliminate shunt-current that feeds into a first therapy module of the medical device via one or more electrodes electrically connected to the first therapy module. The shunt-current may be generated by the delivery of electrical stimulation by a second therapy module. The second therapy module may be enclosed in a common housing with the first therapy module or may be separate, e.g., a part of a separate medical device.

    摘要： A medical device system and associated method discriminate respiratory and cardiac conditions using respiratory sounds. A sensing module acquires a first signal and a second signal, at least the second signal acquired from an acoustic transducer. A processor is configured to receive the first signal and to control the sensing module to acquire the second acoustic signal in response to a change in the first signal. The processor discriminates between a cardiac condition and a respiratory condition as a cause of the change in the first signal in response to the second acoustic signal.

    摘要： Techniques for monitoring T-wave alternans (TWAs) in a patient are described. An implantable medical device (IMD), such as an implantable pacemaker, cardioverter, or diagnostic device, generates an EGM signal, e.g., a far field EGM signal, samples the EGM signal to obtain a single T-wave amplitude value for each T-wave over a plurality of beats, and stores the T-wave amplitude values in memory. The IMD creates a time series of the T-wave amplitude values stored in memory, calculates the power spectral density for the times series, and selects a power spectral density of a particular frequency, e.g., 0.5 cycles per beat, as the TWA value. The IMD may periodically determine TWA values for the patient and store the values in memory. The TWA values may be presented to medical personnel, e.g., as a trend. The IMD may deliver or modify therapy, or provide an alert, based on the TWA values.
