Abstract
Aspects of the present invention are generally directed to impedance spectroscopy in an active implantable medical device (AIMD) comprising a component with one or more electrodes. In an embodiment, the AIMD applies a signal at a plurality of frequencies using one or more of the electrodes. Measurements are then obtained for the applied signal to determine impedance(s) at the applied frequencies of the tissue in which the electrodes are located.
