Abstract
A method and apparatus for preventing fibrillation, particularly atrial fibrillation or flutter. In response to detection of an atrial premature beat at any given site in the atrial chamber, a low energy pulse burst is delivered to multiple sites of at least one chamber of the atrium for a time period sufficient to depolarize the entire atrium. Preferably, multiple pairs of sense electrodes are distributed about an atrial chamber or both atria to define discrete sensing sites and to widely distribute the simultaneously applied pacing energy pulse burst. Bradycardia pacing between the multiple electrode pairs is also preferably provided.
