Nurse charting	Manual atrial fibrillation status
	Atrial fibrillation	No atrial fibrillation	Total
Atrial fibrillation	24	9	33
No atrial fibrillation	1	16	17
Total	25	25	50

^aThe sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were 96% (95% CI 80%-100%), 64% (95% CI 43%-82%), 73% (95% CI 61%-82%), 94% (95% CI 70%-99%), and 80% (95% CI 66%-90%), respectively.
