Abstract
Methods and apparatus for achieving atrial defibrillation in a heart. Atrial pacing is first conducted from multiple pacing sites in an independent (asynchronous) manner so as to have the desired effect of maximizing the extent of phase-locked area of atrial tissue. Next, an ADF shock is introduced, if still needed, to achieve atrial defibrillation. ADFT energy requirements have been shown to be dramatically reduced on account of using pacing rates set proportionally to the sensed local atrial fibrillation cycle lengths such that large areas of atrial tissues are phase-locked, and consequently atrial defibrillation can be effected in the patient with greatly reduced energy requirements for ADFTs.
