    摘要： A medical device and associated method for detecting arrhythmias that includes sensing cardiac electrical signals and cardiac hemodynamic signals, determining a long-term baseline hemodynamic measurement in response to a plurality of the sensed cardiac hemodynaic signals, detecting a period of increased metabolic demand in response to the sensed cardiac electrical signals, determining a sinus tachycardia baseline hemodynamic measurement in response sensing of cardiac hemododynamic signals during the detected period of increased metabolic demand, and detecting the arrhythmia and delivering therapy in response to one of only the sensed cardiac electrical signals and the sensed cardiac electrical signals in combination with one or both of the determined long-term baseline hemodynamic measurement and the sinus tachycardia baseline hemodynamic measurement.

    摘要： Techniques for reducing inappropriate tachyarrhythmia therapy and associated medical device systems are described. In some examples a processor is enabled to receive a cardiac electrical signal representative of electrical activity of a heart of a patient and provide an indication of cardiac electrical signal reliability. A heart sound analyzing module is enabled to receive the indication of cardiac electrical signal reliability and a heart sound signal representing sounds generated by the heart of the patient and generated by a heart sound sensor. The heart sound analyzing module selectively determines an ensemble averaged heart sound signal or detects a plurality of heart sounds from the heart sound signal in response to the indication of cardiac electrical signal reliability.
