System and method for controlling implantable medical device parameters in response to atrial pressure attributes

A dual-chamber pacing implantable medical device comprising:

• a data collection module configured to obtain a left atrial pressure signal from a patient;
• a data processing module coupled to said data collection module, said data processing module being configured to identify at least one attribute of said left atrial pressure signal, and to correlate said at least one attribute to a hemodynamic status of said patient;
• and
• a therapy module coupled to said data processing module, said therapy module being configured to automatically adjust at least one output parameter of a therapy signal in response to said at least one attribute.

A dual-chamber pacing implantable medical device comprising:

• means for obtaining a left atrial pressure signal of a patient;
• means for identifying at least one attribute of said left atrial pressure signal, said at least one attribute being indicative of hemodynamic status of said patient;
• and
• means for automatically adjusting at least one output parameter of a therapy signal in response to said at least one attribute.
