Atrial fibrillation is a common arrhythmia with absent P waves and irregular (irregularly irregular) QRS complexes. The baseline may have coarse or fine fibrillation waves.
Atrial fibrillation should always be described with the rate of ventricular response, e.g. AF with a rapid ventricular response. Slow AF can be a sign of a sick AV node, if the patient is on no rate-slowing medications.
Atrial fibrilation can be paroxysmal, persistent or permanent. It can also be described as valvular or non-valvular. Treatment options include rate control and rhythm control.
Atrial fibrillation is frequently over-diagnosed by machine interpretation, as it tends to mistake baseline / movement artefact for fibrillation waves. Patients with atrial flutter frequently have periods of atrial fibrillation.
