Patent ID: 8718770

Claim:
A method of facilitating selection of at least one vector from among a plurality of vectors for pacing a first chamber of a heart, the method comprising: for each of the plurality of vectors: iteratively delivering, by an implantable medical device controlled by a capture detection module, at least one pacing stimulus at each of a plurality of magnitudes within a predetermined range of magnitudes to the first chamber; for each of the plurality of pacing stimuli, determining, by the capture detection module, if a depolarization occurred in a second chamber of the heart within a predetermined threshold time interval after the pacing stimulus that is less than an intrinsic atrioventricular (AV) interval; identifying, by the capture detection module, a pacing stimulus for which a depolarization in the second chamber does not occur within the predetermined threshold time interval; determining, by the capture detection module, a capture threshold magnitude for the vector based on a magnitude of the pacing pulse for which a depolarization in the second chamber does not occur within the predetermined threshold time interval; and recording, by the capture detection module, the capture threshold magnitudes for the plurality of vectors of the at least one of the plurality of vectors based on the capture threshold magnitudes.
