an implantable device and method for monitoring s1 heart sounds with a remotely located accelerometer . the device includes a transducer that converts heart sounds into an electrical signal . a control circuit is coupled to the transducer . the control circuit is configured to receive the electrical signal , identify an s1 heart sound , and to convert the s1 heart sound into electrical information . the control circuit also generates morphological data from the electrical information . the morphological data relates to a hemodynamic metric , such as left ventricular contractility . a housing may enclose the control circuit . the housing defines a volume coextensive with an outer surface of the housing . the transducer is in or on the volume defined by the housing .
