2024年10月8日 · 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.
Understanding Atrial Fibrillation (AFIB) on an ECG: Key Features …
Atrial fibrillation (Afib) exhibits distinct characteristics on an electrocardiogram (ECG) that aid in diagnosis. A key feature is the absence of P waves, indicating ineffective atrial contraction, along with the presence of irregular R-R intervals, reflecting a chaotic ventricular response.
Atrial Fibrillation ECG Review | Learn the Heart - Healio
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...

2024年10月6日 · avoid calcium channel blockers in decompensated heart failure (digoxin or amiodarone are preferred). Combination of digoxin and a β-blocker recommended for long-term management of compensated heart failure patients. Most textbooks and literature focus on the management of AF in the ward, emergency department, or outpatient setting.
Identifying and Treating Atrial Fibrillation (AFib or AF)
What Are ECG Characteristics of Atrial Fibrillation? Atrial fibrillation is generally considered a tachyarrhythmia, (an arrhythmia with a heart rate of more than 100 beats per minute). Patients experiencing atrial fibrillation generally have the following characteristics: P waves are absent; The QRS complex is narrow (less than 0.12 seconds)

2024年3月26日 · Atrial fibrillation (Afib) is a common type of supraventricular tachyarrhythmia characterized by uncoordinated atrial activation that results in an irregular ventricular response. While the exact m...
ECG Basics: Atrial Fibrillation With Rapid Ventricular Response
This is a good basic rhythm strip example of atrial fibrillation with a rapid ventricular response showing the identifying characteristics of atrial fibrillation: no P waves, an irregularly-irregular rhythm, and a "fibrillatory" baseline.
