Claim:
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.
