Noninvasive estimation of the end systolic pressure-volume relationship using impedance cardiography.

TL;DRAbstract

A noninvasive method for estimating the ESPVR that differentiates the myocardial contractile state in the clinically setting was derived using parameters obtained from IC. While further studies are needed to correlate this new equation with invasive measurements, this method has the potential for easily estimating load independent contractility in patients with cardiac dysfunction.
