Abstract
A controller detects a cyclic cardiac event of the patient based on a signal obtained from one or more electrodes configured for placement on or near a diaphragm, and delivers an electrical stimulation therapy to a diaphragm of the patient through the one or more electrodes. The delivery of electrical stimulation therapy is timed to the detection of the cyclic cardiac event, and the electrical stimulation therapy is defined by stimulation parameters. The controller monitors a pressure associated with the intrathoracic cavity of the patient based on a signal provided by a pressure measurement source configured to provide a signal indicative of a pressure within an intrathoracic cavity, to determine whether an adjustment of one or more of the stimulation parameters is warranted.
