Below are a collection of excerpts from biomedical research articles. Excerpts are separated by newlines. Your task is to answer a question based these excerpts. Your response should be formatted as a `json` array.

For instance, given excerpts from articles studying breast cancer, and the question "what are some common genes associated with breast cancer?", an answer might be formatted like: ["BRCA1", "BRCA2", "TP53", ...]. Only include answers that are mentioned in the provided exerpts. The array should always have at least one answer; do not respond with an empty array []. Do not include any text in your response other than the answer array.

Context: Atrial fibrillation (AF) is the most common sustained arrhythmia and is associated with significant morbidity and mortality. Multiple conditions like hypertension, heart failure, diabetes, sleep apnoea, and obesity play a role for the initiation and perpetuation of AF.
Atrial fibrillation is the most common arrhythmia worldwide with increasing frequency noted with age. Hyperthyroidism is a well-known cause of atrial fibrillation with a 16%-60% prevalence of atrial fibrillation in patients with known hyperthyroidism
Atrial fibrillation continues to be a challenging arrhythmia. There are some conventional, time-tested explanations of atrial fibrillation genesis, however some uncertainty of its complete understanding still exists. We focused on atrial ischemia which, hypothetically, could be responsible for manifestation of the arrhythmia, irrespective of the underlying heart disease
The prevalence of atrial fibrillation (AF) increases with age. As the population ages, the burden of AF increases.
t is estimated that this arrhythmia's suffers a significant increase throughout the entire life span, and that its highest raise occurs between the ages of 65 and 80.
Drug-induced tachyarrhythmias (ventricular tachycardia or atrial tachyarrhythmias with rapid ventricular response) are life-threatening and often cause syncope
Atrial fibrillation is a growing health problem and the most common cardiac arrhythmia, affecting 5% of persons above the age of 65 years.
It occurs very often in patients with congestive heart failure and the prevalence increases with the severity of the disease.
The prevalence and incidence of atrial fibrillation increase with age.
Cardiac arrhythmias are a major problem in elderly persons, because of the high prevalence of underlying heart disease and hypertension,
Heavy alcohol use has been suspected to cause acute atrial fibrillation,
Heavy alcohol use is an important potential etiology for acute atrial fibrillation; alcohol withdrawal may represent a particular risk for such alcohol-related atrial fibrillation.
Atrial fibrillation associated with rheumatic mitral valve disease has the highest stroke risk (about 17 times greater than unaffected controls), but even with nonvalvular heart disease, the risk is increased fivefold
hronic atrial fibrillation is a very common arrhythmia affecting 2 to 4% of the population older than 60 years of age
In western countries ischemic and hypertensive heart disease (including sick sinus syndrome) and alcohol (holiday heart syndrome) are numerically more important than the classical causes of atrial fibrillation--rheumatic heart disease and thyrotoxicosis-
Risk factors for acute atrial fibrillation include increasing age, cardiovascular disease, alcohol, diabetes, and lung disease.
Risk factors for acute atrial fibrillation include increasing age, cardiovascular disease, alcohol, diabetes, and lung disease
Diabetes mellitus is frequently accompanied by cardiac rhythm disorders. On the other hand, atrial fibrillation is the most frequent cardiac arrhythmia in adult population
isk factors for acute atrial fibrillation include increasing age, cardiovascular disease, alcohol, diabetes, and lung disease.
Risk factors for atrial fibrillation include increasing age, male sex, co-existing cardiac and thyroid disease, pyrexial illness, electrolyte imbalance, cancer, and co-existing infection.
Risk factors for atrial fibrillation include increasing age, male sex, co-existing cardiac and thyroid disease, pyrexial illness, electrolyte imbalance, cancer, and co-existing infection
Risk factors for atrial fibrillation include increasing age, coexisting cardiac and thyroid disease, pyrexial illness, electrolyte imbalance, cancer, and coexisting infection.
Thus, pericarditis might play a role in the development of recent atrial fibrillation during the course of myocardial infarction. Recent atrial fibrillation may be a sign of pericardial effusion which may be otherwise silent.
Some patients develop atrial fibrillation after any type of surgery, some patients develop atrial fibrillation only after cardiac surgery, and still other patients never develop postoperative atrial fibrillation
Hypertension is known to increase the risk of atrial fibrillation
Of the long list of various cardiac conditions associated with an increased risk of cardioembolic strokes, non-valvular atrial fibrillation is the most common cause.

Please list 10 conditions which play a role in causing atrial fibrillation.
