1. A method comprising:

  • determining that fibrillation is occurring in a heart of a person;

    defibrillating the heart without applying shock pulses by;

    applying electrical pulses to the heart at a rate greater than about 10 Hz, with a peak power that is less than about 100 W, wherein applying the pulses comprises applying a pulse having an amplitude less than about 50 mA, andterminating the electrical pulses, whereby the steps of applying and terminating the electrical pulses effectuate defibrillation of the heart;

    sensing motion of the heart, wherein applying the pulses comprises modifying a characteristic of at least some of the pulses applied to the heart responsive to the sensed motion; and

    pacing the heart at approximately 1 Hz while applying the electrical pulses at the rate greater than about 10 Hz.
