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.

Aug 2, 2023 · A doctor can identify some types of atrial fibrillation by looking at an electrocardiogram, or EKG. Learn about their characteristics and how they are identified in this MNT Knowledge Center...

Sep 25, 2023 · See inside a heart during atrial fibrillation. WebMD shows the causes, tests, and treatments for this common heart rhythm problem through illustrations and photos.

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...

Mar 28, 2025 · One of our most popular pages on A-Fib.com is Understanding the ECG/EKG Signal. The post last week about the Vektor Medical vMap system that uses the common ECG to locate non-PV A-Fib triggers made me think it may be time to review the ECG. Every patient with Atrial Fibrillation is familiar with a electrocardiogram, ECG.

Learn about the EKG signal and the special EKG grid paper used to represent a graphical image of the electrical activity of your heart.

Search for an EKG strip from a simple drop down list. Quickly find any rhythm and click go. It will pull up a page with an example strip and an easy to understand deicription. No lengthy deep learning. No digging. Just find your strip fast and easy!

Feb 2, 2025 · Interpreting an Afib ECG strip is a fundamental skill for healthcare professionals. By understanding the key features of Afib, such as irregular rhythm, absent P waves, and fibrillatory waves, you can accurately diagnose this common arrhythmia.

Atrial fibrillation is when multiple electrical impulses are being generated in the atria at the same time. This causes chaotic myocardial responses that may diminish both the pre-load and effectiveness of the cardiac contraction.
