A trail fibrillation is the commonest sustained cardiac arrhythmia. It accounts for >35% of all hospital admissions for cardiac arrhythmias. The presence of atrial fibrillation increases the mortality of a population by up to twofold. The risk of stroke increases from 1.5% in patients with atrial fibrillation from 50–59 years of age to up to 23.5% for such patients aged 80–89 years. Atrial fibrillation is the commonest cardiac arrhythmia. It affects 5% of people above the age of 65 years and 10% above 75.The most important mor-bidity and mortality associated with atrial fibril-lation result from stroke. The attributable risk of stroke increased from 1.5% for patients with atrial fibrillation aged 50–59 years to 23.5% for those aged 80–89 years. It is also associated with congestive heart failure.
