Key result
Hypokalemia is linked to a ~124% higher incidence of daily AF compared to normokalemia.

Does hypokalaemia increase the incidence of daily atrial fibrillation in at-risk individuals undergoing continuous ECG monitoring?

Low plasma potassium is associated with an increased day-to-day occurrence of atrial fibrillation, particularly for longer episodes, in at-risk individuals.

Relative Risk: 2.24 (95% CI 1.29–3.88)
Low plasma potassium is associated with an increased day-to-day occurrence of atrial fibrillation, particularly for longer episodes, in at-risk individuals.
Hessellund et al. (2025) conducted an observational in Atrial fibrillation (n=1,334). Hypokalaemia (plasma potassium <3.5 mmol/L) vs. Normal range plasma potassium was evaluated on Daily atrial fibrillation > 60 min (IRR 2.24, 95% CI 1.29-3.88). Hypokalaemia was associated with a higher incidence of daily atrial fibrillation compared to normal potassium levels (IRR 2.24; 95% CI 1.29-3.88).
