Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

This is an electrogram mapping study that tests the ability of a new signal processing technique called electrogram morphology recurrence mapping to locate drivers in participants with atrial fibrillation. This study will also test the hypothesis that there are non-invasive markers that can predict driver location. Electrogram mapping will be performed in participants undergoing ablation for persistent atrial fibrillation. These participants will have a cardiac MRI and 12-lead ECG prior to the ablation procedure.
