Key result
Hypokalemia is linked to an ~83% higher risk of atrial fibrillation.
Why the study?
Little is known about the association of serum potassium levels with the risk of atrial fibrillation.
Is low serum potassium associated with an increased risk of atrial fibrillation in hospitalized patients?
Comparison
Hypokalaemia (serum potassium < 3.5 mmol/l) vs normal serum potassium levels
Design
Retrospective case-control study

Low serum potassium (<3.5 mmol/l) is significantly associated with an increased risk of atrial fibrillation in hospitalized patients.
Farah et al. (2020) conducted a case-control in Atrial fibrillation (n=541). Hypokalemia (< 3.5 mmol/l) vs. Normal serum potassium was evaluated on Atrial fibrillation (OR 1.827, 95% CI 1.50-3.179, p=0.02). Low serum potassium levels (< 3.5 mmol/l) were significantly associated with an increased risk of atrial fibrillation (OR 1.827; 95% CI 1.50-3.179; p=0.02).
