Abstract
A leadless cardiac pacemaker (LCP) configured to sense cardiac activity and to pace a patient's heart. The LCP may include a housing, a first electrode secured relative to the housing, a second electrode secured relative to the housing, and a pressure sensor secured relative to the housing and coupled to the environment outside of the housing. The LCP may further include circuitry in the housing in communication with the first electrode, the second electrode, and the pressure sensor. The circuitry may be configured to determine and store a plurality of impedance-pressure data pairs, from which a representation of a pressure-volume loop may be determined.
