1. A method of locating a source of a rhythm disorder of a heart, the method comprising:

  • processing a first pair of cardiac signals to define a first coefficient associated with variability among the first pair of signals at a first region of the heart;

    processing a second pair of cardiac signals to define a second coefficient associated with variability among the second pair of signals at a second region of the heart; and

    comparing the first coefficient of variability to the second coefficient of variability to determine a direction towards the source of the rhythm disorder;

    wherein variability is determined independent of activation onsets within the signals.
