Abstract
An apparatus for determining cardiac performance in the patient involving a conductance catheter () for measuring conductance and blood volume in a heart chamber of the patient. The apparatus includes a processor () for determining instantaneous volume of the ventricle by applying a non-linear relationship between the measured conductance and the volume of blood in the heart chamber to identify mechanical strength of the chamber. The processor () is in communication with the conductance catheter ().
