Atrial Fibrillation
What is atrial fibrillation?
Atrial fibrillation (AF), also called Afib, is a condition which causes an irregular and often rapid heart rate, and can lead to stroke and heart failure. It is one of a group of heart rhythm conditions called arrhythmias, which are caused by changes to the heart’s electrical impulses.
In a healthy heart, regular electrical signals keep your heart rate at a steady rhythm of between 60 and 100 beats per minute. This is called sinus rhythm. When you have AF, the electrical signals become random and chaotic, causing the top two chambers of your heart (the atria) to twitch or quiver. This in turn causes your heart rate to become irregular and can cause it to beat faster than usual.
