CARDIAC FUNCTION CHANGE EVALUATING DEVICE

摘要

Provided is a cardiac function change evaluating device comprising a continuous flow type auxiliary artificial heart (20) connected to a ventricle (10A), a pressure sensor (30) for detecting the pressure in the ventricle (10A), and means (or a personal computer (40)) for evaluating the change in a ventricular systole while the auxiliary artificial heart (20) being worn, on the basis of a closed loop area (APMp) of the relation between the ventricular pressure detected by the pressure sensor (30) and the electric power consumed by the auxiliary artificial heart (20). As a result, the change in the ventricular systole while the auxiliary artificial heart (20) being worn can be continuously evaluated by a non-invasive method without using an ultrasonic echo device or a conductance catheter.
