Abstract

The present invention relates to a method for operating an implantable ventricular assist system (2), comprising the following steps: a) determining a first impedance parameter at a first time point with the aid of the assist system (2), b) determining a second impedance parameter at a second time point with the aid of the assist system (2), c) determining a change in the impedance parameter using at least the first impedance parameter and the second impedance parameter, or comparing at least the first impedance parameter or the second impedance parameter with a threshold value.
