(A) Distribution of noise in all atrial fibrillation (AF) episodes |
Duration of noise in AF episode | Number of episodes | Proportion of all episodes |
---|---|---|
0% | 18 | 27.3% |
1–5% | 36 | 54.5% |
6–10% | 3 | 4.5% |
11–15% | 5 | 7.6% |
15–20% | 4 | 6.1% |
(B) Proportion of correct RR intervals in AF episodes and the median duration of all corresponding AF episodes |
Number of correct RR intervals in the episode (×1000) | Proportion of all AF episodes | Median duration of AF episodes (min) |
---|---|---|
1–1.5 | 16.7% | 11.0 |
1.5–2.5 | 16.7% | 17.9 |
2.5–5 | 27.3% | 29.3 |
5–10 | 15.2% | 58.2 |
>10 | 24.2% | 269.0 |
Median rather than the mean, which can skew the result owing to a few exceptionally long AF episodes.
