Specialised definition of the noun atrial fibrillation

Glossary of healthcare

a chaotic rhythm of the heart that causes the two upper chambers of the heart (atria) to beat rapidly and irregularly; only part of the contraction reaches the lower chamber (ventricles)

  • note: The condition can cause an increased risk of blood clots and stroke.

Explanation

Atrial Fibrillation: A supraventricular arrhythmia characterized by uncoordinated atrial myocardium activation due to multiple reentry circuits with consequent deterioration of atrial mechanical function. Instead of intermittently contracting, the atria quiver continuously in a chaotic pattern, causing a totally irregular, often tachycardia ventricular rate. On the ECG it is described by the replacement of consistent P waves by rapid oscillations or fibrillatory waves that vary in size, shape, and timing, associated with an irregular, frequently rapid ventricular response when atrioventricular conduction is intact.
