Abstract
To monitor a patient for rejection reactions of an implanted heart, a permanent magnet is implanted epicardially in the heart wall and a magnetically active semiconductor element, preferably a Hall generator, is implanted endocardially. Movement of the heart wall results in changes in the distance between the permanent magnet and the semiconductor element. An implantable component supplies the semiconductor element with current and measures the signal generated by the movement of the heart wall. The measured values are transmitted electromagnetically out of the body by the component and recorded extracorporeally, and stored for data transmission.
