1. A method for delivering therapy in a medical device, comprising:
- determining the presence of a lead-related condition;
determining, in response to a lead-related condition being present, the presence of oversensing; and
controlling deliver of therapy in response to the lead-related condition and oversensing being present.

Abstract
A method for delivering therapy in a medical device that 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. Deliver of therapy by the medical device is controlled in response to determining that both the lead-related condition and oversensing are present.

14. A method for delivering therapy in a medical device, comprising:
-
determining whether a first oversensing criteria is satisfied;
determining whether a second oversensing criteria is satisfied;
determining whether an impedance criteria has been satisfied;
generating an alert in response to more than one of the first oversensing criteria, the second over sensing criteria and the impedance criteria being satisfied;
sensing cardiac signals and detecting cardiac events via a first electrode configuration in response to more than one of the first oversensing criteria, the second over sensing criteria and the impedance criteria being satisfied;
determining the presence of an episode event in response to the detected cardiac events;
sensing the cardiac signals via a second electrode configuration;
determining predetermined values associated with cardiac signals sensed via the second electrode configuration corresponding to the event episode; and
controlling delivery of therapy in response to the determined values. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23)
