Table 7.
Exploratory analysis on test set 2a, evaluating effect of using all available leads (rather than only 1 lead shown in for automated atrial fibrillation detection.
| Automated algorithm atrial fibrillation status | Manual atrial fibrillation status | ||
| Atrial fibrillation | No atrial fibrillation | Total | |
| Atrial fibrillation | 25 | 1 | 26 |
| No atrial fibrillation | 0 | 24 | 24 |
| Total | 25 | 25 | 50 |
aThe sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were 100% (95% CI 86%-100%), 96% (95% CI 80%-99.9%), 96% (95% CI 79%-99%), 100% (95% CI 76%-98%), and 98% (95% CI 89%-99.9%), respectively.
