Abstract
A cardiac function variation evaluation apparatus includes: a continuous flow type auxiliary artificial heartconnected to a ventricle (A); a pressure sensorfor detecting ventricle (A) internal pressure; and means (a personal computer) for evaluating contractile variation of the ventricle, to which the auxiliary artificial heartis connected, based on internal area APMp of a closed-loop of a relationship between the ventricle internal pressure detected by the pressure sensorand a consumption power of the auxiliary artificial heart. Thus, the contractile variation of the ventricle, to which an auxiliary artificial heart is connected, can be continuously evaluated not by use of an ultrasonic echo apparatus or a conductance catheter but by use of a non-invasive method.
