The present invention relates to open-loop and closed-loop control units for extracorporeal circulatory support, to systems comprising such an open-loop and closed-loop control unit, and to corresponding methods. An open-loop and closed-loop control unit (10) for extracorporeal circulatory support is proposed, which is configured to receive a measurement of an ECG signal (12) of a supported patient over a predefined period of time, wherein the ECG signal (12) comprises multiple data points for each time point within a heart cycle. The open-loop and closed-loop control unit (10) comprises an evaluation unit (100) which is configured to evaluate the data points for at least one time point in a spatial and/or temporal manner and to determine at least one amplitude change (14) within the heart cycle based on the evaluated data points. The open-loop and closed-loop control unit (10) is further configured to output an open-loop and/or closed-loop signal (16) for extracorporeal circulatory support at a predefined point in time after the at least one amplitude change (14).
