Explore Atrial Fibrillation
Atrial fibrillation (AF) occurs if the heart's electrical signals don't travel through the heart in a normal way. Instead, they become very rapid and disorganized.
The risk of AF increases as you age. Inflammation also is thought to play a role in causing AF.
Sometimes, the cause of AF is unknown.
Clinical trials are research studies that explore whether a medical strategy, treatment, or device is safe and effective for humans. To find clinical trials that are currently underway for Atrial Fibrillation, visit www.clinicaltrials.gov.
