Atrial fibrillation

Symptoms, stroke risk, treatment

Summary

Atrial fibrillation (AFib) is an irregular heart rhythm that raises stroke risk. Many patients feel palpitations, fatigue, or shortness of breath, but some have no symptoms at all. Treatment focuses on stroke prevention, rhythm or rate control, and managing underlying conditions like high blood pressure or sleep apnea.
