Changes in electrocardiogram parameters in the left and right PV reconnection groups
| Baseline | Just after the procedure | Repeat procedure | p‐value | |
|---|---|---|---|---|
| P‐wave duration (maximum) | ||||
| Left PV reconnection (n = 70) | 130.1 ± 12.5 ms | 116.8 ± 12.5 ms* | 128.4 ± 14.5 ms† | <.001 |
| Right PV reconnection (n = 84) | 127.9 ± 12.4 ms | 117.1 ± 11.7 ms* | 126.0 ± 14.0 ms† | <.001 |
| Both left and right PVs reconnection (n = 54) | 129.3 ± 13.0 ms | 117.6 ± 12.5 ms* | 128.3 ± 14.9 ms† | <.001 |
| P‐wave duration (signal‐averaged electrocardiogram) | ||||
| Left PV reconnection (n = 70) | 132.2 ± 14.5 ms | n.a. | 135.4 ± 15.2 ms | .062 |
| Right PV reconnection (n = 84) | 131.0 ± 14.5 ms | n.a. | 133.0 ± 15.2 ms | .189 |
