Abstract

A method and apparatus for treating fibrillation, particularly atrial fibrillation. In response to detection of fibrillation, a series of low energy pulse bursts is delivered, separated by defined inter-burst intervals, and including bursts unsynchronized to heart depolarizations.
Detection of termination of fibrillation during inter-burst intervals results in cancellation of further pulse bursts to prevent re-induction of fibrillation.
