Atrial Fibrillation — What Is It and How Is It Treated

This patient-facing multimedia article explains atrial fibrillation (AF) the most common sustained cardiac arrhythmia its symptoms, health risks, and modern treatment options. Experts describe AF as an irregular rhythm originating in the upper chambers of the heart, often causing fatigue, palpitations, dizziness, and elevated stroke risk due to clot formation. The video features a panel of cardiologists discussing the evolution of AF management, including anticoagulation therapy to reduce stroke risk, rate and rhythm control strategies, and the growing role of catheter ablation for symptom relief and rhythm restoration. Emphasis is placed on shared decision-making and tailoring treatment based on patient preferences, symptom severity, and coexisting conditions. The segment includes illustrative visuals for patients and families to understand the electrophysiology of AF and its impact, with an empathetic tone toward living well with the diagnosis.
