Table 3. Groupings and counts of patient-level mechanisms (by row), as well as the assignment of the patient group for survival analysis in Fig 8, based on whether a patient contains initiator-type FS coming from a single atrium.
This table omits the results of patients with driver-type FS for clarity.
| Mechanism | Initiator-type FS | Sustained AF without FS | Count | |
|---|---|---|---|---|
| from LA/PVs | from RA | |||
| Group 1 (Single-atrial initiator-type FS) | ✔ | ✔ | 13 (25%) | |
| ✔ | ✔ | 14 (27%) | ||
| Group 2 (Other mechanisms) | ✔ | ✔ | ✔ | 11 (21%) |
