1. A method for treating fibrillation in a heart of a patient, the patient having an external body surface, the method comprising;

  • measuring the fibrillation from the body surface by sensing heart cycle signals while no intracardiac probe is present in the heart;

    locating an arrhythmogenic region of the heart in response to the measured fibrillation such that the arrhythmogenic region is determined using the sensed heart cycle signals prior to intracardiac access; and

    directing treatment at or near the arrhythmogenic region so that the fibrillation is inhibited.
