Diastolic left ventricular function Experimental study of the early filling period using the Voigt model.

Background: The left ventricular (LV) diastolic function is usually described by the diastolic part of the LV pressure-volume relationship (PVR). The mathematical analysis of the PVR provides parameters of diastolic LV as well as myocardial function. Up to now, all approaches assume the myocardium as a passive elastic medium.
