End Diastolic Pressure Volume Relationship (EDPVR) relates to the passive filling curve of the left ventricle during diastole and is a measure of passive chamber stiffness (see attached citations). The slope of EDPVR is the reciprocal of compliance and is used to measure ventricular stiffness. A decrease in compliance may be related to ventricular hypertrophy, and an increase in compliance might be related to a dilated cardiomyopathy.
