Abstract
An implant predicts decompensation of a patient's heart based on an acoustic pressure measurement. The implant includes first and second acoustic transducers, which are matched to each other and which rest in/on the patient's thorax. The first acoustic transducer emits an acoustic signal which has at least one first signal portion having a first frequency. The second acoustic transducer is designed to receive and re-emit the emitted acoustic signal, or to reflect it, such that the first acoustic transducer receives the emitted acoustic signal. A signal processing unit communicates with at least one of the two acoustic transducers and determines an attenuation value as a function of the attenuation of the received acoustic signal versus the originally emitted acoustic signal, and provides a prediction signal as a function of a comparison of the attenuation value to a threshold value, wherein the prediction signal indicates the development of decompensation.
