Abstract: The present disclosure relates to a method for monitoring an implantable device (200, 500, 601, 602). The method comprises: receiving at least one cardiac vector signal (230-1, 230-2), wherein the at least one cardiac vector signal is acquired by the implantable device between at least one pair of electrodes (213, 212); extracting two or more separate features (A, B, C, J) from the at least one cardiac vector signal by signal processing; deriving a hardware status (pnoise) of the implantable device based at least in part on a classification of the extracted two or more separate features.
