Atrial fibrillation is the most common type of irregular heartbeat (arrhythmia). It is caused by an abnormal rhythm in the upper chambers of the heart (the atria).
Atrial fibrillation causes uncomfortable symptoms and increases your risk of other serious medical conditions, including more heart rhythm problems, heart failure and stroke.
Understand what happens inside your heart during atrial fibrillation as well as symptoms and possible causes.
Your doctor may order several tests that measure and record the electrical activity of your heart, including an electrocardiogram or heart monitor.
We provide safe and effective treatment options for patients with atrial fibrillation, including stroke prevention, heart medication and heart ablation techniques.
