AF Information & Advice For Patients
What is Atrial Fibrillation?
Atrial Fibrillation (AF) is the most common heart rhythm disorder (arrhythmia) encountered by doctors. It occurs when chaotic electrical activity develops in the upper chambers of the heart (the atria). As a result, the atria no longer beat in an organised, regular rhythm, the pulse is irregular and as a result, the pumping of the heart is less efficient.
