Signal‐Averaged P‐Wave Values of Patients
| AF (+) (n = 19) | AF (−) (n = 81) | P value | |
|---|---|---|---|
| P‐wave duration (msn) | 117 ± 21 | 107 ± 19 | 0.02 |
| LP 20 (μV) | 2.5 ± 2 | 2.8 ± 2.7 | NS |
| Abnormal P‐SAECG | 7 (37%) | 12 (15%) | 0.04 |
LP 20: root‐mean‐square voltage for the last 20 ms of the signal‐averaged P wave.
NS: not significant, P > 0.05.
