What is AF?

What is AF?

Atrial fibrillation (AF) is an abnormality in the rhythm of the heart (an arrhythmia). It involves the upper chambers of the heart, the atria, beating irregularly. As the atria controls the normal (sinus) rhythm of the heart, this means that your pulse becomes irregular.

AF is the most common arrhythmia, affecting four out of every 100 people over the age of 65. AF occurs when chaotic electrical activity develops in the atria, and completely takes over from the sinus node. As a result, the atria no longer beat in an organized way, and pump less efficiently. The AV node (a specialized cluster of heart cells) will stop some of these very rapid impulses from travelling to the ventricles, but the ventricles will still beat irregularly and possibly rapidly. This may contribute to symptoms of palpitations, shortness of breath, chest discomfort, light headedness, fainting or fatigue.

The goal of treatment for AF is to restore the heart’s normal rhythm and if this is not possible, then to slow the irregular heart rate, to alleviate symptoms and prevent complications of AF.
