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%.

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.

Jan 26, 2022 · 12-lead ECG: the diagnostic investigation for AF. Typical features include tachycardia (particularly in new-onset), irregularly irregular rhythm, absent P-waves, fibrillation waves (best seen in lead II and V1) and a chaotic baseline. Ambulatory ECG: if suspected paroxysmal AF to capture a symptomatic episode.

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...

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”)

Jan 14, 2021 · At the AV node 'every now and then' a beat is conducted to the ventricles, resulting in an irregular ventricular rate, which is the typical ECG characteristic of atrial fibrillation. Sometimes atrial fibrillation results in a course atrial flutter …

Atrial flutter typically involves one stable reentrant circuit that leads to regular and predictable atrial behaviour. However, there is a very common rhythm known as atrial fibrillation (AF/A-Fib) characterized by erratic activation of the atria known as fibrillatory conduction.
