Overview
Atrial fibrillation must be distinguished from other common atrial arrhythmias. These include:
- Atrial flutter
- Atrial tachycardia
- Atrioventricular nodal reentry tachycardia (AVNRT)
- Multifocal atrial tachycardia
- Paroxysmal supraventricular tachycardia
- Wolff-Parkinson-White syndrome
Diagnosis
- Atrial fibrillation is irregularly irregular, while the other rhythms such as atrial flutter, sinus tachycardia, AV nodal reentry tachycardia in paroxysmal supraventricular tachycardia are all much more regular.
- An atrioventricular nodal reentry tachycardia will often break with either carotid sinus massage or AV nodal blocking agents.
- If the patient has Wolff-Parkinson-White syndrome there may be much more rapid conduction.
