1. A method to define a driver of a source associated with a cardiac rhythm disorder of a human heart, the method comprising:

  • processing a plurality of cardiac signals associated with sensors arranged spatially in relation to an area of the heart to determine a sequence of arcs of rotation in relation to the sensors over a time interval;

    determining rotational directions of the arcs of rotation in the sequence; and

    identifying and displaying on a graphical display the area of the heart as associated with controlling the source when the rotational directions of the arcs of rotation in the sequence continue in a same rotational direction in excess of a threshold of a magnitude of rotation determined by a phase analysis.
