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|τ) in each case of values X(t+τ) for which X(t)=x applies for their predecessors, τ describing a time interval, and determining the phase-specific parameters by evaluating the mean g(x|τ).

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:
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.
