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.

Abstract
An implantable medical device is configured to detect saturation events from a cardiac electrical signal, detect a tachyarrhythmia based at least in part on the cardiac electrical signal, responsive to detecting the tachyarrhythmia, and compare the detected saturation events to lead issue criteria. If the detected saturation events satisfy lead issue criteria, a therapy for treating the tachyarrhythmia is withheld by the implantable medical device.
