Patent ID: 8491485

Claim:
An electromedical implant including: a. a detector configured to obtain: (1) a first measurement signal (S 1 ) associated with a cardiac blood flow (B 1 ) of a living being, and (2) a second measurement signal (S 2 ) associated with an epithoracic, peripheral blood flow (B 2 ) of the living being, the second measurement signal (S 2 ) being an impedance signal; b. a monitoring assembly in communication with the detector, the monitoring assembly being configured to obtain: (1) a first parameter (P 1 ) from the first measurement signal (S 1 ) representative of a time (t sys ) at which blood is ejected from the heart, and (2) a second parameter (P 2 ) from the second measurement signal (S 2 ) representative of a time (t gef ) of a blood pulse in the thoracic tissue which is associated with the ejection of blood; c. an evaluation unit in communication with the monitoring assembly, the evaluation unit being configured to generate a pulse transit time (Δt) from the first parameter (P 1 ) and the second parameter (P 2 ).
