1. A method of cardiac signal analysis in an implantable cardiac stimulus system having at least first and second sensing electrodes defining a first sensing vector therebetween, the method comprising:

  • selecting a detection threshold;

    capturing a plurality of detected events in which an electrical signal sensed along the first sensing vector exceeds the detection threshold;

    analyzing at least one metric related to a signal to noise ratio and amplitude for the plurality of detected events; and

    determining whether the first sensing vector is;

    suitable for cardiac event detection;

    unsuitable for cardiac event detection;

    oravailable for cardiac event detection.
