1. A method for delivering therapy in a medical device, comprising:
- determining, prior to detection of a sustained tachyarrhythmia episode, whether a lead-related condition is present;
adjusting, in response to determining the lead-related condition is present, at least one parameter used to determine whether oversensing is present;
detecting the sustained tachyarrhythmia episode;
if the lead-related condition is present, determining, in response to the detection of the sustained tachyarrhythmia episode, whether oversensing is present using the at least one parameter that was adjusted in response to determining the lead-related condition is present;
withholding delivery of a shock therapy to treat the sustained tachyarrhythmia episode in response to both determining that the lead-related condition is present and determining that oversensing is present; and
delivering the shock therapy in response to determining that the lead-related condition is present and determining that oversensing is not present.

Abstract
A method for delivering therapy in a medical device includes a two-tiered approach of determining the presence of a lead-related condition, and determining, in response to a lead-related condition being present, the presence of oversensing. Delivery of therapy by the medical device is controlled in response to determining that both the lead-related condition and oversensing are present.

12. A system comprising:
-
at least one lead; and an implantable medical device coupled to the at least one lead and including at least one processor configured to; determine, prior to detection of a sustained tachyarrhythmia episode, whether a lead-related condition is present; adjusting, in response to determining the lead-related condition is present, at least one parameter used to determine whether oversensing is present; detecting the sustained tachyarrhythmia episode; if the lead-related condition is present, determine, in response to the detection of the sustained tachyarrhythmia episode, whether oversensing is present using the at least one parameter that was adjusted in response to determining that the lead-related condition is present; withhold delivery of a shock therapy to treat the sustained tachyarrhythmia episode in response to both determining that the lead-related condition is present and determining that oversensing is present; and deliver the shock therapy in response to determining that the lead-related condition is present and determining that oversensing is not present. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)

22. A non-transitory computer-readable medium comprising instructions that, when executed by a processor, cause the processor to:
-
determine, prior to detection of a sustained tachyarrhythmia episode, whether a lead-related condition is present; adjusting, in response to determining the lead-related condition is present, at least one parameter used to determine whether oversensing is present; detecting the sustained tachyarrhythmia episode; if the lead-related condition is present, determine, in response to the detection of the sustained tachyarrhythmia episode, whether oversensing is present using the at least one parameter that was adjusted in response to determining the lead-related condition is present; withhold delivery of a shock therapy to treat the sustained tachyarrhythmia episode in response to both determining that the lead-related condition is present and determining that oversensing is present; and deliver the shock therapy in response to determining that the lead-related condition is present and determining that oversensing is not present. - View Dependent Claims (23)
