Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The study is conducted in patients with atrial fibrillation undergoing clinically prescribed ablation. The study hypothesis is that ablation at specific sites that are identified to 'drive' the atrial fibrillation may improve the success of the ablation procedure.
