Abstract: An implantable medical device includes an integrated or connectable implantable three-dimensional acceleration sensor, and a ballistocardiogram (BCG) capturing unit that is connected or connectable to the acceleration sensor. The BCG evaluation unit processes an acceleration signal provided by the acceleration sensor and derives a BCG from the 3D accelerometer output signal. A BCG evaluation unit is connected to the BCG capturing unit, and is designed to evaluate a BCG provided by the BCG capturing unit and supply an output signal representing stroke volume.

Abstract: A medical device includes a preload determination unit for determining the preload of a ventricle for a cardiac cycle and providing a preload value representing the preload; a contractility determination unit for determining the contractility of the ventricle for the cardiac cycle and providing a contractility value representing the contractility; and an evaluation unit connected to the preload determination unit and the contractility determination unit, with the evaluation unit being configured to evaluate contractility values versus associated preload values.

Abstract: An implantable medical device includes a multi-axial acceleration sensor and an evaluation unit connected thereto. The evaluation unit is configured to (1) split the accelerometer output signal into at least two signal components, one of which is associated with a right-ventricular contraction and another of which is associated with a left-ventricular contraction; (2) detect events in the signal components, and/or determine signal features therein; and (3) determine at least one characteristic value K by evaluating the signal components, and/or the events and/or signal features therein.

Abstract: The invention relates to methods and systems for determining phase-specific parameters of a physiological variable, and a related computer program and a related machine-readable storage medium, which are usable in particular to determine parameters of physiological variables that are subject to circadian variation. To this end, phase-specific parameters of a physiological variable X(t) are determined by calculating, at least for a portion of values x lying in a specifiable time period, a mean g(x|?) in each case of values X(t+?) for which X(t)=x applies for their predecessors, ? describing a time interval, and determining the phase-specific parameters by evaluating the mean g(x|?).

Abstract: An implantable device includes a posture sensor and a physiological signal sensor. The posture sensor supplies at least one first sensor output signal indicating body posture and/or changes therein. The physiological signal sensor supplies at least one second sensor output signal indicative of at least one physiological parameter such as blood pressure, intracardiac impedance, stroke volume, heart sounds, heart rate, and/or biochemical measurements (e.g., oxygen concentration). An evaluation unit processes the first and second sensor output signals and determines one or more variables that describe the dynamic behavior of the second sensor output signal in response to a change in body posture indicated by the first sensor output signal.
