Claim Text:
1. A method for use with an implantable medical device for implant within a patient, the method comprising: measuring values representative of ventricular cardiogenic impedance and deriving E-wave parameters representative of passive filling of the ventricles of the heart of the patient from the ventricular cardiogenic impedance values, wherein deriving E-wave parameters from the ventricular cardiogenic impedance values includes: measuring values representative of atrial cardiogenic impedance and deriving A-wave parameters representative of active filling of the ventricles from the atrial cardiogenic impedance values; assessing diastolic function based on the E-wave parameters and the A-wave parameters; and controlling at least one device function based on the assessment of diastolic function.
