Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Following a single ablation procedure, there were no recorded instances of atrial arrhythmias (such as atrial fibrillation, atrial tachycardia, or atrial flutter) or events of less than 30 seconds duration, excluding the initial 3-month blanking period, during the 12-month period following the procedure and without the use of AADs.; | — |
