What is Atrial Fibrillation? Symptoms, Causes and Treatment

Atrial fibrillation (AF) is a heart rhythm disorder characterized by irregular and often rapid contractions of the heart's upper chambers. The incidence of AF increases with age, affecting approximately 1 in 20 people over 65.

The most noticeable symptoms of AF include palpitations, chest discomfort, shortness of breath, and fatigue. The most serious complication of AF is stroke. Blood thinners are typically prescribed for AF patients.

Treatment has three main goals: reducing stroke risk, controlling heart rate, and restoring normal rhythm. Lifestyle changes are also an important part of treatment.
