Cardiac Arrhythmias in Greenland

The study is a phd-study comprising several substudies focusing on cardiac arrhythmias, mainly atrial fibrillation, among Greenlanders in Greenland. Some previous studies have indicated that the prevalence may be lower than among Westerners, however; studies have also indicated that atrial fibrillation is underdiagnosed. These studies aim to: * Estimate the prevalence of AF among Greenlanders in Greenland aged 55 years or older. * Estimate the prevalence of well-known risk factors among those found to have AF * Explore the symptoms of those affected by AF in Greenland * Among part of the participants: estimate the prevalence of autonomic neuropathy as this may cause arrhythmias.
