Abstract :
An IBM-PC controlled system has been developed to evaluate the cardiac function in the catheterization room. The system uses a multielectrode impedancimetric catheter to compute the instantaneous left intraventricular heart volume, through specially developed algorithms and calibration procedures, and a catheter tip micromanometer to measure the instantaneous left intraventricular pressure. With these two variables, and after a preload maneuver, the slope of the end-systolic pressure-volume relationship is obtained. This parameter has been postulated to be a load-independent index of cardiac function.<>
