Understanding Atrial Fibrillation: Causes, Symptoms, and Treatment Methods

Overview of Atrial Fibrillation

The heart has four chambers: two atria and two ventricles, separated by a septum to ensure proper blood flow. The right atrium receives deoxygenated blood from the body, and the left atrium receives oxygen-rich blood from the lungs. The heart's rhythm is regulated by the sinoatrial (SA) node, acting as a natural pacemaker. Disruptions here can cause irregular heartbeats, such as atrial fibrillation (AFib).

Atrial fibrillation results in the atria beating chaotically and rapidly, reducing blood efficiency. While often not immediately dangerous, AFib increases the risk of heart failure, strokes, and other health issues. It can be episodic (paroxysmal) or persistent, requiring treatment. Common symptoms include irregular heartbeat, chest pain, dizziness, fatigue, and breathlessness; some individuals may not show symptoms. Early medical help is vital, especially if chest pain occurs, indicating a potential heart attack.

Management focuses on restoring normal heart rhythm, controlling the heart rate, preventing blood clots, and minimizing stroke risk. Treatments include medications, electrical shocks, or invasive procedures. Anti-arrhythmic drugs like Amiodarone, Dofetilide, and Propafenone are used to restore rhythm (cardioversion). Electrical cardioversion uses shocks to reset the heart. Catheter ablation targets abnormal electrical pathways by destroying problematic tissue. Surgical options, such as Maze procedures, create scar tissue to block irregular signals. Blood thinners like Rivaroxaban, Apixaban, Dabigatran, and Warfarin help prevent clots, with careful medical oversight. Proper treatment enables many individuals to live active, healthy lives despite AFib.
