Why is it important?
Hypokalemia, hypomagnesemia, and hyperthyroidism can lead to acute atrial fibrillation and QTc prolongation.
Perspectives
In patients with clinically stable AF detected in the emergency department, electrolyte and thyroid function tests must be analyzed before initiating drug therapy.
