Abstract:
1. A cardiac rhythm management system, comprising: a cardiac resynchronization optimization module configured to determine pacing parameters for cardiac resynchronization therapy (CRT); pacing therapy circuitry configured to deliver pacing using the CRT pacing parameters; a pulmonary artery pressure sensor having dimensions to fit within the pulmonary artery and configured to sense pulmonary artery pressure; a right ventricular function analysis module configured to analyze the measured pressure to determine right ventricular function achieved during the pacing; and a controller configured to generate a signal responsive to a change in the right ventricular function during the pacing, wherein the cardiac resynchronization optimization module comprises a processor configured to implement the right ventricular function analysis module and to generate an alert if the right ventricular function degrades, the processor further configured to allow an override of the selected one or more pacing parameters to achieve an improvement in the right ventricular function.
