Keywords
persistent atrial fibrillation, catheter ablation, CARTO-Finder-guided ablation, Multiscale entropy-guided ablation
Brief summary
This is a randomized control trial to compare the efficacy and safety of CARTO-Finder-guided ablation plus pulmonary vein isolation versus multiscale entropy (MSE)-guided pulmonary vein isolation in patients with persistent atrial fibrillation.
Detailed description
This is a randomized control trial. Patients with persistent atrial fibrillation are enrolled and randomized to CARTO-Finder-guided ablation plus PVI group or MSE-guided ablation plus PVI group. Postoperative recurrence rate and other indicators are analyzed to compare the efficacy and safety between CARTO-Finder-guided ablation plus PVI and MSE-guided ablation plus PVI in patients with persistent atrial fibrillation.
Interventions
The multiscale entropy is calculated based on intracardiac electrical signals, higher multiscale entropy value indicates closer to the core of rotors which maintains the persistent atrial fibrillation.
