Abstract:
Systems and methods for detecting events indicative of worsening using heart sounds are disclosed. A system can include a signal sensor circuit to sense a heart sound (HS) signal. The system can detect at least first and different second HS components using the HS signal, and generate respective first and second HS metrics. The system can determine a trend indicator for the first or second HS metric, and selectively generate one or more composite HS metrics using the first and second HS metrics, according to the trend indicator indicating a growing or decay trend. The system can include a heart failure (HF) event detector to produce a HF status using the composite HS metrics, and output an indication of the HF status, or deliver therapy according to the HF status.

Claim (Index 20):
A system, comprising:\n means for receiving cardiac acceleration information of a patient; means for generating a first signal metric and a second signal metric different than the first signal metric using the received cardiac acceleration information; means for generating a composite metric using (1) a ratio of the second signal metric to the first signal metric or (2) a product of the first and second signal metrics; and means for detecting a heart failure (HF) status using a combination of (1) at least one of the first or second signal metric and (2) the generated composite metric.
