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.

Sep 25, 2023 · The way to confirm AFib is with an electrocardiogram (EKG). The machine detects and records the electrical activity of your heart, so your doctor can see problems with its rhythm.

Atrial flutter has the typical “sawtooth pattern,” whereas multifocal atrial tachycardia requires three distinct P wave morphologies in one 12-lead ECG tracing. Note that there are quite a few...

Nov 8, 2021 · This article is a guide for the ECG interpretation of Atrial Fibrillation, including a sample ECG strip. This is our online abnormal ECG interpretation cheat sheet!

The key distinguishing factor is the presence of more organized atrial activity (i.e. p waves with atrial tachycardia, or F waves with atrial flutter) as opposed to the fibrillatory waves of AF. The ECG below demonstrates AFL with variable block and rapid rate (~102 bpm).

Learn how to interpret an ECG showing atrial fibrillation (AFib). Understand the irregular heart rhythm and its implications. Explore more now!

Atrial fibrillation (AF) is a supraventricular tachyarrhythmia caused by disorganised electrical activity in the atria, leading to ineffective atrial contraction. It is characterised by an irregularly irregular pulse, and the absence of distinct P waves on an ECG.
