Abstract:
1. A method of selecting a default sensing vector for use with an implantable cardiac stimulus device system, the system comprising: an implantable medical device adapted to define a plurality of sensing vectors between electrodes implanted in a patient, and a programmer adapted for communication with the implantable medical device, the method comprising: the implantable medical device capturing cardiac signal data using at least one of the plurality of sensing vectors; (x) analyzing data related to the captured cardiac signal data to establish a set of detections separated by intervals, the set of detections including a first detection in time and a series of detections occurring after the first detection; (y) analyzing the set of detections by identifying the first detection in time as a QRS peak and, for the remaining detections performing the following until a predetermined number of QRS peaks are identified: (z) if a score is generated in step (y), comparing the score to a threshold and,
