Patients with atrial fibrillation are faced with an increased risk of thromboembolic events, myocardial infarction, chronic heart failure and death. For some patients with atrial fibrillation, direct current cardioversion (DCCV) is a strategy that can be used to reacquire sinus rhythm.

The prospective study includes patients with electrocardiographically confirmed atrial fibrillation who underwent direct current cardioversion, hospitalised at Pauls Stradiņš Clinical University Hospital (Rīga, Latvia).
