Raymond Farah, Mais Nassar, Bayan Aboraya, William Nseir: Low serum potassium levels are associated with the risk of atrial fibrillation (Acta Cardiol . )

Atrial fibrillation (AF) is the most common sustained arrhythmia in clinical practice. AF is associated with approximately a threefold to fivefold increased risk for stroke. Hypokalaemia is associated with ventricular arrhythmias and cardiac arrest. Little is known about the association of serum potassium with atrial fibrillation. The aims of this study are to assess the association of low serum potassium (hypokalaemia) and the risk of AF.
