Abstract
An implantable medical device system and method are provided for monitoring the quality of signals sensed by a subcutaneously implanted device using subcutaneous electrodes. In one embodiment, the method includes selecting one or more sensing vectors; sensing signals from selected sensing vectors, determining a signal quality metric in response to a sensed signal, comparing the signal quality metric to a predetermined threshold, and generating a loss of signal quality response in response to the signal quality crossing the threshold.
