Diagnostic measures of the 6-lead ECG of the device for the detection of AF.
| Measure | AF vs. stable SR group (n = 214) | AF vs. both SR groups including frequent PVCs/PACs (n = 341) |
|---|---|---|
| Sensitivity (%), (95% CI) | 99.2 (95.4–100) | 99.2 (95.4–100) |
| Specificity (%), (95% CI) | 100 (96.2–100) | 99.1 (96.8–99.9) |
| Accuracy (%), (95% CI) | 100 (-) | 99.1 (97.4–99.8) |
| LR (+), (95% CI) | - | 110.07 (27.70–437.41) |
| LR (-), (95% CI) | 0.01 (0.00–0.06) | 0.01 (0.00–0.06) |
AF, atrial fibrillation; SR, sinus rhythm; PVC, premature ventricular contraction; PAC, premature atrial contraction; LR (+), positive likelihood ratio; LR (-), negative likelihood ratio.
