Results of the test set 2^a for automated atrial fibrillation signal and noise detection and R–R interval indices, with added P-wave and premature beat detection, from unselected waveforms.

Automated algorithm atrial fibrillation status	Manual atrial fibrillation status
	Atrial fibrillation	No atrial fibrillation	Total
Atrial fibrillation	23	1	24
No atrial fibrillation	2	24	26
Total	25	25	50

^aThe sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were 92% (95% CI 74%-99%), 96% (95% CI 80%-100%), 96% (95% CI 77%-99%), 92% (95% CI 76%-98%), and 94% (95% CI 83%-99%), respectively.
