Oct 8, 2024 · Atrial fibrillation (AF) is the most common sustained arrhythmia. It is characterised by disorganised atrial electrical activity and contraction. The incidence and prevalence of AF is increasing. Lifetime risk over the age of 40 years is ~25%.

Atrial fibrillation occurs when action potentials fire very rapidly within the pulmonary veins or atrium in a chaotic manner. The result is a very fast atrial rate — about 400 to 600 beats per...

This chapter discusses the classification, causes (electrophysiology), ECG /EKG diagnosis, risk factors and management (treatment) of atrial fibrillation. Includes a complete e-book, video lectures, clinical management, guidelines and more.

Oct 6, 2024 · Atrial fibrillation (AF) is the most common sustained dysrhythmia and is characterised by disorganised atrial electrical activity and contraction resulting in an “irregularly irregular” ventricular response (“fibrillation waves”)

Feb 2, 2025 · Atrial fibrillation (AF) is the most common sustained arrhythmia in clinical practice, with a prevalence in developed countries close to 2% of the general population. Atrial fibrillation consists of the appearance of disorganized stimuli at atria, with rates from 350 to 600 bpm.
