title: [Atrial dissociation in complete intra-atrial block].
abstract: Atrial dissociation due to a complete intraatrial block is a very rare electrocardiographic occurrence. Two cases of this atrial arrhythmia characterized by two atrial ectopic beats of different origin are reported. The electrophysiologic mechanisms of the arrhythmia are discussed briefly.
