Claim:
1. An implantable medical device, comprising: sensing circuitry to receive a first cardiac electrical signal via electrodes carried by a medical electrical lead when the medical electrical lead is coupled to the implantable medical device; therapy delivery circuitry to deliver a tachyarrhythmia therapy to a patient's heart; and a control module coupled to the sensing circuitry and the therapy delivery circuitry and configured to: detect one or more saturation events from the first cardiac electrical signal; detect a tachyarrhythmia based at least in part on the first cardiac electrical signal; responsive to detecting the tachyarrhythmia, compare the detected saturation events to lead issue criteria; and withhold the tachyarrhythmia therapy when the lead issue criteria are satisfied.
