Patent ID: 7704209

Claim:
A system, comprising: means for sensing a cardiac electrogram (EGM) signal of the heart; means for sensing a right ventricular pressure (RVP) signal; means for computing an estimated stroke volume using the sensed EGM signal and the sensed RVP signal; wherein the means for computing an estimated stroke volume comprises means for computing a RVP pulse contour integral by: identifying an integration start time corresponding to an estimated time of pulmonic valve opening; identifying an integration end time corresponding to an estimated time of pulmonic valve closure; and computing a plurality of correction areas used to adjust the area under the right ventricular pressure signal between the integration start time and the integration end time; and means for one of displaying and storing in a memory structure at least one of: the RVP pulse contour, the estimated stroke volume, the right ventricular pressure signal, the area.
