A troubleshooting method can identify potential sources of noise emanating from an implanted portion of a medical system. The method, which may be carried out by the system, for example, according to pre-programmed instructions, includes a step of collecting at least one EGM sample from a sensing pair of electrodes, and an EGM sample from each of a plurality of recording pairs of electrodes. The sensing pair may be formed by first and second electrodes of an implanted lead, and the plurality of recording pairs include pairs formed by each of the lead electrodes and an electrode of an implanted device. Following collection, the EGM samples from the recording pairs may be analyzed for the presence or absence of noise and, then, potential noise sources may be determined.
