Abstract

The invention relates to a method for detecting a state of wear of a cardiac support system. The method comprises a read-in step and a determination step. During the read-in step, a sensor signal (315) representing an operating state of the cardiac support system is read in. During the determination step, a wear signal (325) is determined using the sensor signal (315) and a comparison rule (320). The wear signal (325) represents the wear condition.
