Atrial fibrillation (AF) is a common cardiac arrhythmia characterized by rapid and irregular beating of the atria, leading to inefficient blood flow in the heart. This condition is a major concern because it can result in serious complications, such as stroke and heart failure, due to the formation of blood clots from stagnant blood in the atria. Understanding AF is crucial for managing patient care effectively, particularly regarding its symptoms, risks, and treatment options.
