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.
