Potassium cho Cardiac Arrhythmia

C Bằng chứng Bằng chứng hạn chế từ các nghiên cứu nhỏ, nhưng có một số tín hiệu tích cực.

Hypokalemia is a well-established arrhythmia trigger. Guidelines support maintaining serum K+ >4.0 mEq/L. Research on supplementation benefit in normokalemic patients is unclear.
