The present study has derived a new method for estimating the maximum value (E/sub max/) of the ventricular elastance (E(t)) without direct measurement of the ventricular volume (V(t)) by regarding the estimation process as an inverse problem. The me

A new method for less invasive and beat-by-beat estimation of the maximum ventricular elastance (E max) is proposed. The method (parameter optimization method) needs only two measurements: aortic pressure and flow. In the estimation process, the leas
