• Atrial arrhythmias arise from the following mechanisms:
Premature atrial beat (e.g. premature atrial contraction and atrial geminy)
Atrial escape beat (e.g. atrial escape beat or rhythm and wandering atrial pacemaker)
Tachycardia-induced atrial ectopic beat (e.g. atrial tachycardia, multifocal atrial tachycardia and atrial fibrillation)
Reentry-induced atrial ectopic beat (e.g. atrial flutter)
• Examples of atrial arrhythmias are listed below.
