摘要：
A medical system includes two or more leadless implantable medical devices, each implanted in a different ventricle of the heart and each including 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. Each of the leadless implantable medical devices may further include circuitry in the housing operatively coupled to the corresponding first electrode, second electrode, and pressure sensor. The medical system may be configured to determine and store a plurality of pressure-pressure data pairs and/or impedance-impedance data pairs generated by the two or more leadless implantable medical devices, from which a representation of a pressure-pressure loop or volume-volume loop may be determined, to facilitate cardiac resynchronization therapy (CRT), patient health status monitoring, and/or the management of a non-CRT cardiac therapy.
