Abstract
An implantable medical device for generating a cardiac pressure-volume loop, the implantable medical device comprising a pulse generator including control circuitry, a first cardiac lead including a proximal end and a distal end and coupled to the pulse generator at the proximal end, a first electrode located at the distal end of the cardiac lead and operatively coupled to the control circuitry, a sound sensor operatively coupled to the control circuitry, and a pressure sensor operatively coupled to the control circuitry, wherein the implantable medical device is adapted for measuring intracardiac impedance. A method of using the implantable medical device to optimize therapy delivered to the heart.
