How long can you live with atrial fibrillation?
Posted 4 years ago in Heart Health by Mydog


Atrial fibrillation is not usually fatal though the person with this disease is more likely to suffer from palpitations, fainting, chest pain, or congestive heart failure. People with atrial fibrillation are also seven times more likely to suffer from a stroke which can be life-threatening.

What is Atrial Fibrillation

Atrial fibrillation is an abnormal heart rhythm. The heart's electrical system normally sends regularly spaced, predictable signals, telling the heart muscle to contract, or beat.

The heart has two upper chambers, called atria, and two lower chambers, called ventricles. Each signal starts in the atria and travels to the rest of the heart. In atrial fibrillation, the electrical signals from the atria are fast and irregular. The atria quiver, rather than contract. Some signals do not reach the ventricles and the ventricles continue pumping, usually irregularly and sometimes rapidly. This uncoordinated rhythm can reduce the heart's efficiency at pumping blood out to the body. Blood left in the heart chambers can form clots. These clots may sometimes break away, travel to the brain, and cause a Stroke.
