Abstract
A method and system are provided for characterizing cardiac function. The method and system comprise collecting cardiac signals associated with electrical or mechanical behavior of a heart over at least one cardiac cycle; identifying a timing feature of interest (FOI) from the cardiac signals; collecting dynamic impedance (DI) data over at least one cardiac cycle (CC), designated by the timing FOI, along at least one of i) a venous return (VR) vector or ii) a right ventricular function (RVF) vector; and analyzing at least one morphologic characteristic from the DI data based on at least one of i) a VR-DI correlation metric to obtain a VR indicator associated with the CC or ii) a RVF-DI correlation metric to obtain a RVF indicator associated with CC.
