Abstract
Systems and methods for recognizing and tracking heart sound components are disclosed. An exemplary medical-device system comprises a data receiver circuit to receive heart sound information, and a heart sound recognition circuit to generate a representative heart sound segment within a cardiac cycle, such as an ensemble average of a plurality of heart sound segments taken from multiple cardiac cycles. The heart sound recognition circuit can partition the representative heart sound segment into multiple heart sound data windows, calculate spectral entropy values respectively for each of the multiple heart sound data windows, and determine one or more heart sound components including an S2 component using the calculated spectral entropy values. A physiologic event detector can detect a cardiac event using the recognized one or more heart sound components.
