Atrial fibrillation (also called AFib or AF) is a quivering or irregular heartbeat (arrhythmia) that can lead to blood clots, stroke, heart failure and other heart-related complications. Some people refer to AF as a quivering heart. An estimated 2.7 million Americans are living with AF.
Here???s how patients have described their experience:
???My heart flip-flops, skips beats, and feels like it???s banging against my chest wall, especially if I???m carrying stuff up my stairs or bending down.???
???I was nauseated, light-headed, and weak. I had a really fast heartbeat and felt like I was gasping for air.???
???I had no symptoms at all. I discovered my AF at a regular check-up. I???m glad we found it early.???
What happens during AFib?
atrial fibrillationNormally, your heart contracts and relaxes to a regular beat. In atrial fibrillation, the upper chambers of the heart (the atria) beat irregularly (quiver) instead of beating effectively to move blood into the ventricles. About 15???20 percent of people who have strokes have this heart arrhythmia.
???Anything that allows blood to slow down or pool increases the risk of clotting, and so increases the risk of stroke,??? says Dr. Steve Roach, Professor of Neurology and Director of the Comprehensive Epilepsy Program at Wake Forest University Medical School.
If a clot breaks off, enters the bloodstream and lodges in an artery leading to the brain, a stroke results.??? This clot risk is why patients with this condition are put on blood thinners. People with atrial fibrillation have an increased stroke risk of about five percent per year.???
It's the most common "serious" heart rhythm abnormality in people over the age of 65 years. Even though untreated atrial fibrillation doubles the risk of heart-related deaths and causes a 4???5-fold increased risk for stroke, many patients are unaware that AF is a serious condition.
