Patent ID: 7831303

Claim:
A method of providing pacing capture management in an implantable medical device, the method comprising: delivering a pacing therapy through at least one lead; monitoring for secondary indicators of loss of pacing capture; performing a pacing threshold search if a secondary indicator of loss of pacing capture is monitored determining whether the secondary loss of pacing capture indicator more likely indicates a loss of pacing capture in an atrium or more likely indicates a loss of pacing capture in a ventricle; and performing the pacing threshold search on the atrium first if the secondary loss of pacing capture indicator more likely indicates a loss of pacing capture in an atrium and performing the pacing threshold search on the ventricle first if the secondary loss of pacing capture indicator more likely indicates a loss of pacing capture in a ventricle wherein the secondary indicators of loss of pacing capture include atrial sensed events, the atrial sensed events include an increased frequency of sensed atrial refractory events, an increased frequency of PVARP extensions, a detected pattern of retrograde conduction, an increased frequency of mode switching, or an increased duration of non-atrial tracking episodes.
