Claim Text:
1. A medical device system for determining pacing threshold data, comprising: a cardiac capture sensor; a phrenic nerve stimulation sensor; a pulse generator selectively coupled to a plurality of electrode vectors to deliver a pacing stimulation pulse; and a processor coupled to the cardiac capture sensor, the phrenic nerve stimulation sensor and the pulse generator and configured to deliver the pacing simulation pulse along the plurality of electrode vectors, determine, for each vector of the plurality of vectors, a pacing capture threshold in response to the delivered pacing pulse, deliver a phrenic nerve stimulation pulse along only the vectors of the plurality of vectors that the determined pacing capture threshold is less than a predetermined pacing capture threshold limit, and determine whether phrenic nerve stimulation is detected in response to the delivered phrenic nerve stimulation pulse.
