During the contraction phase of the myocardium the cardiac muscle reaches its maximum state of activation near end-systole at point (Pm, Vm) on the PV-loop. The tangent to the PV-loop at (Pm, Vm) is known as the end-systolic pressure-volume relation

Relations between the ejection fraction (EF), parameters describing the end-systolic pressure-volume relation (ESPVR) and the areas under the ESPVR are derived for a linear model of the ESPVR. The active pressure generated by the myocardium during an

A formula derived by using large elastic deformation for the contraction of the myocardium is used to describe the pressure-volume relation (PVR) in the heart left ventricle, it is also used to calculate a mathematical expression for the non-linear e

A mathematical formalism for the non-linear end-systolic pressure-volume relation (ESPVR) in the heart ventricles has the interesting feature that the peak active pressure generated by the myocardium (also called peak isovolumic pressure P isom by ph

The problem of heart failure with normal or preserved ejection fraction (HFpEF) has been the subject of numerous studies. Mathematical relations between ejection fraction (EF) and the parameters describing linear and non-linear end-systolic pressure-
