Device and method for monitoring and optimising a temporal trigger stability (WO2023094554A1)
(2023)
The present invention relates to devices for monitoring and optimising a temporal trigger stability of an extracorporeal circulatory support means, and to open-loop and closed-loop control units for the extracorporeal circulatory support means comprising such a device, and to corresponding methods. A device (10) for monitoring a temporal trigger stability of an extracorporeal circulatory support means is accordingly proposed, which device is designed to receive a first dataset (14) of a measurement of an ECG signal of a supported patient over a predefined period of time. The device (10) comprises an evaluation unit (16), which is designed to determine or identify a plurality of R triggers (26) from the first dataset (14), wherein the evaluation unit (16) is also designed to receive or provide a second dataset (20) having evaluated ECG signals and a plurality of R triggers (28) and to selectively map the second dataset (20) on the first dataset (14). The device is also designed to emit a signal (22) that characterises a temporal gap between successive R triggers (26) from the first dataset (14) and successive R triggers (28) from the second dataset (20) which are mapped on the first dataset.
