Abstract
A system and method for evaluating cardiac performance relative to performance of an intrathoracic pressure maneuver is described. Blood pressure is indirectly sensed by directly collecting intracardiac impedance measures through an implantable medical device. Cardiac functional changes to the blood pressure are evaluated in response to performance of an intrathoracic pressure maneuver.
