15 lis 2011 · Atrial fibrillation (AF), the most common sustained cardiac arrhythmia, is an important contributor to population morbidity and mortality. An arrhythmia that is particularly common in the elderly, AF is growing in prevalence with the aging of the population. Our understanding of the basic mechanisms that govern AF occurrence and persistence has ...
Our review focuses on the epidemiology and pathophysiology of AF rather than its clinical treatment. 1. Pathophysiology and Natural History AF. AF is characterized by high frequency excitation of the atrium that results in both dyssynchronous atrial contraction and irregularity of ventricular excitation.
8 mar 2024 · During atrial fibrillation, the heart's upper chambers — called the atria — beat chaotically and irregularly. They beat out of sync with the lower heart chambers, called the ventricles. For many people, AFib may have no symptoms.
25 kwi 2014 · The pathophysiology of AF centers around 4 general types of disturbances that promote ectopic firing and reentrant mechanisms, and include the following: (1) ion channel dysfunction, (2) Ca 2+ -handling abnormalities, (3) structural remodeling, and (4) autonomic neural dysregulation.
AF may be classified based on aetiology, depending on whether it occurs without identifiable aetiology in patients with a structurally normal heart (lone AF), or whether it complicates hypertensive, valvar, or other structural heart disease.
7 kwi 2022 · Atrial fibrillation (AF) is the most common cardiac arrhythmia despite substantial efforts to understand the pathophysiology of the condition and develop improved treatments. Identifying the...
