The disclosure describes systems, methods, and apparatus providing detection mechanism for lead-related conditions, including transient behaviors, on a conductive pathway of a medical electrical lead. In one example, a sense path arbitration module identifies a lead-related condition associated with a conductive pathway based on signal processing to identify transients emerging from a propagated signal. The sense path arbitration module may evaluate a plurality of conductive pathways of the medical electrical lead and arbitrates propagation of a sensed signal that is transmitted through the plurality of lead conductors based on the evaluation. Therapy delivery functions utilizing the medical electrical lead may also be controlled in response to the signal processing and identification of the lead-related condition on a conductive pathway.
