Patent ID: 7507208

Claim:
A method, comprising: sensing a cardiac electrogram (EGM) signal of the heart; sensing a right ventricular pressure (RVP) signal; computing an estimated stroke volume using the sensed EGM signal and the sensed RVP signal; wherein computing an estimated stroke volume comprises 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; computing the area under the right ventricular pressure signal between the integration start time and the integration end time; and wherein computing the RVP pulse contour comprises 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 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.
