Atrial Fibrillation (AF, or ciliary arrhythmia) is a type of supraventricular tachyarrhythmia with chaotic electrical activity of the atria with a pulse frequency of 350-700 per minute, which leads to the lack of the possibility of coordinated contraction of the atria and ventricles. AF is one of the most common arrhythmias. The risk of AF increases with aging. AF can be detected by determining the pulse and finding that the heartbeats occur at an irregular interval. The final diagnosis is established when recording the ECG, where P waves are absent and F waves are recorded.

The frequency of ventricles contractions with atrial fibrillation depends on the electrophysiological properties of the AV node, the level of sympathetic and parasympathetic nervous system activity, and the effects of medications. This arrhythmia is often associated with structural pathology of the heart. The lack of coordinated atrial systole in AF increases the risk of thromboembolic complications (stroke in the first instance). Atrial fibrillation leads to a significant increase in morbidity, mortality and cost of treatment. In particular, AF chronicity leads to an increase in the risk of death by approximately 1.5-2 times.
The established diagnosis of atrial fibrillation or the appearance of symptoms similar to the symptoms of atrial fibrillation require medical intervention to assess the risks of complications and determine the therapeutic approach.
