<unk>  is the most common arrhythmia and<unk> fects more than 33 million people worldwide. In Europe and North America, , it<unk> fects about 2% to 3% of the population. This is an increase from 0.4 to 1% of the population around 2005. In the developing world, rates are about 0.6% for males and 0.4% for females. The number of people diagnosed with<unk>  has increased due to better detection of silent<unk>  and increasing age and conditions that predispose to it. It also accounts for one-third of hospital admissions for cardiac rhythm disturbances, and the rate of admissions for<unk>  has risen in recent years.<unk>  is the cause for 20% to 30% of all ischemic strokes.<unk> ter a transient ischemic attack or stroke, about 11% are found to have a new diagnosis of<unk> . 3% to 11% of patients with<unk>  have structurally normal hearts. Approximately 2.2 million individuals in the United States and 4.5 million in the European Union have<unk> . The number of new cases each year of<unk>  increases with age. In people older than 80 years, it<unk> fects about 8%. In contrast, in younger people the prevalence is estimated to be 0.05% and is associated with congenital heart disease or structural heart disease in this demographic. As of 2001, it was anticipated that in developed countries, the number of people with<unk>  was likely to increase during the following 50 years, due to the growing proportion of elderly peolpe. Sex<unk>  is more common in men than in women when reviewed in European and North American populations. In Asian populations and both developed and developing countries, there is also a higher rate in men than in women. The risk<unk> ctors associated with<unk>  are also distributed differently according to sex. In men, coronary disease is more frequent, while in women, high systolic blood pressure and valvular heart disease are more prevalent. Ethnicity Rates of<unk>  are lower in populations of<unk> rican descent than in populations of European descent.<unk> rican descent is associated with a protective effect for<unk> , due to the lower presence of SNPs with guanine alleles. European ancestry has more frequent mutations. The variant rs4611994 for the gene PITX2 is associated with risk of<unk>  in<unk> rican and European populations. Hispanic and Asian populations have a lower risk of<unk>  than European populations. The risk of<unk>  in non-European populations is associated with characteristic risk<unk> ctors of these populations, such as hypertension. Young people<unk>  is an uncommon condition in children but sometimes occurs in association with certain inherited and acquired conditions. Congenital heart disease and rheumatic fever are the most common causes of<unk>  in children. Other inherited heart conditions associated with the development of<unk>  in children include Brugada syndrome, short QT syndrome, Wolff Parkinson White syndrome, and other forms of supraventricular tachycardia (e.g., AV nodal reentrant tachycardia). Adults who survived congenital heart disease have an increased risk of developing<unk> . In particular, people who had atrial septal defects, Tetralogy of<unk> llot, or Ebstein's anomaly, and those who underwent the Fontan procedure, are at higher risk with prevalence rates of up to 30% depending on the heart's anatomy and the person's age.
