Abstract
An electrode connectivity determination system is coupled to a plurality of patient attachable electrodes. Such a system includes a comparator for performing a comparison of a low frequency differential signal derived from at least two of the patient attachable electrodes with a predetermined threshold signal and a decision processor for generating a signal indicating an electrode signal is at least potentially degraded in response to said first comparison.
