At least 2.7 million people in the U.S. are living with atrial fibrillation, according to the American Heart Association. And because the risk of developing it increases with age and people are living longer, medical researchers predict the frequency will rise dramatically over the next few years.
Atrial fibrillation is an irregular and often rapid heart rhythm that can lead to blood clots in the heart. Atrial fibrillation increases the risk of stroke, heart failure and other heart-related complications.
Some people with atrial fibrillation don't notice any signs or symptoms. Those who do may have sensations of a fast, fluttering or pounding heartbeat; chest pain; dizziness or lightheadedness; and shortness of breath.
