    Atrial Fibrillation Overview

    Atrial fibrillation is an irregular heartbeat that increases the risk of stroke and heart disease. Signs include dizziness, weakness, and fatigue. Treatment involves medication and lifestyle changes, and sometimes procedures such as cardioversion, ablation, pacemakers, or surgery.

    Symptoms

    Atrial fibrillation is often discovered during routine medical checkups, because many people don't have symptoms. Others may notice an irregular pulse but don't have other symptoms.

    Mild symptoms of atrial fibrillation may occur immediately. More serious problems may occur after the start of atrial fibrillation and over the course of several days. So it is important to identify symptoms and get treatment as soon as possible.
