Abstract: This invention relates to a method and system for determining and/or tracking a heart function of a patient. wherein the heart function is estimated by combining information representative of an electrical, mechanical and/or hemodynamic heart function received from imaging, therapy and/or diagnosis systems or a patient database with real-time information representative of an electrical, mechanical and/or hemodynamic heart function received from a measuring device attached or implanted to the patient. The information and the real-time information from can be associated to update an evaluation of the heart function of the patient in real-time and thereby improve the heart function and possibly optimize its efficiency.

Abstract: Described herein are systems and methods for assessing a condition of a mechanical circulatory support device (MCSD). The systems and methods can be used for early detection of device malfunction. The system can include a sensing subsystem that can obtain from one or more sensors signals indicative of at least one of vibrations or acoustics of the MCSD in operation in the mammal. The system can also include a computing subsystem. The computing subsystem can receive the signals indicative of at least one of the vibrations or the acoustics of the MCSD in operation in the mammal. process the signals to identify at least one harmonic in the signals, and evaluate the condition of the MCSD using the at least one harmonic identified in the signals indicative of at least one of the vibrations or the acoustics of the MCSD in operation in the mammal.

Abstract: The approach presented here relates to a determination appliance (100) for determining a viscosity of a fluid. The determination appliance (100) has at least one determination device (110) and a provisioning device (115). The determination device (110) is designed to determine the viscosity of the fluid and/or a rotational speed (ω) of a blade wheel (205) for conveying the fluid by using at least one detected volume flow of the fluid and a detected pressure difference of the fluid. The provisioning device (115) is designed to provide or send a viscosity signal (130) representing the viscosity determined by the determination device (110).
