Atrial fibrillation is an arrhythmia that is characterized by the chaotic and unpredictable contraction of muscle fibers in the atrium. The resulting dyssynchrony leads to a loss of contractile function. As a consequence, there is a predisposition to atrial coagulation and, accordingly, the risk of thromboembolic stroke increases. It is well known that this arrhythmia increases mortality and morbidity. Thus, its prevention and treatment are crucially important for both patients and the health-care system in general.
