Parameters Pressure-volume loop experiments

calculation of edpvr , espvr

edpvr , espvr valuable because load-independent indices of left ventricular function. measure left ventricle compliance/stiffness (edpvr) , contractility (espvr) respectively.

other parameters derived series of loops are:

time-varying elastance
end-systolic elastance called maximal elastance
preload recruitable stroke work
preload adjusted
