Overview
Atrial fibrillation (AFib) is a type of irregular heartbeat that affects the upper chambers (atria) of the heart. It is caused by disorganized electrical signals that make the heart beat in a fast and irregular manner. This condition can lead to complications such as stroke, heart failure, and other heart-related problems. The symptoms of AFib include palpitations, shortness of breath, dizziness, and fatigue. The diagnosis is usually made through an electrocardiogram (ECG) and other tests. Treatment may include medications, such as blood thinners, and procedures such as cardioversion, catheter ablation, or surgical intervention. Lifestyle changes such as maintaining a healthy weight, quitting smoking, and reducing alcohol intake can also help manage this condition.
