A method and apparatus for adjusting the electrogram (EGM) sensitivity level of an implantable medical device using intracardiac pressure data. An EGM is monitored to detect electrical events and intracardiac pressure is monitored to detect pressure waves. The electrical waves and pressure waves are analyzed to determine the presence of a one-to-one correlation, with the absence of a one-to-one correlation indicating the need to adjust the sensitivity level.
