1. A device, comprising:

  • a morphology analyzer adapted to extract and measure sensed cardiac complex parameter values;

    a template generating circuit connected to the morphology analyzer and adapted to receive the sensed cardiac complex parameter values and generate a cardiac complex template; and

    a template comparison circuit connected to the template generating circuit and adapted to compare sensed cardiac complex parameter values to reference cardiac parameter values to determine if the sensed cardiac complex parameter values and the reference cardiac parameter values have a difference greater than a threshold,wherein the template comparison circuit and the template generating circuit cooperate to update the cardiac complex template upon determining that the difference is greater than the threshold.
