We hypothesized that AF mechanisms may be clarified if mapping techniques were compared in the same patients, and referenced to a clinical endpoint. We compared two independent AF mapping techniques in patients in whom ablation terminated persistent AF before pulmonary vein isolation (PVI).<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods and Results<\/jats:title><jats:p>We identified 12 patients with persistent AF (61.2 \u00b1 10.8 years, four female) in whom mapping with 64 pole baskets and technique 1 (activation\/phase mapping, FIRM) identified rotational activation patterns during at least 50% of the 4\u2010second mapping interval and targeted ablation at these rotational sites terminated AF to sinus rhythm (n = 10) or atrial tachycardia. We analyzed the unipolar electrograms of these patients to determine phase maps of activation by an independent technique 2 (Kuklik, Schotten <jats:italic>et\u00a0al<\/jats:italic>., IEEE Trans Biomed Eng 2015). Compared to technique 1, technique 2 revealed a source in 12 of 12 (100%) cases with spatial concordance in all cases (P &lt;0.05) and similar rotational characteristics.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>At sites where ablation terminated persistent AF, two independent mapping techniques identified stable rotational activation for multiple cycles that drove peripheral disorder. Future comparative studies referenced to a clinical endpoint may help reconcile if discrepancies between AF mapping studies reports represent techniques, patient populations or models of AF, and improve mapping to better guide ablation.<\/jats:p><\/jats:sec>","DOI":"10.1111\/jce.13177","type":"journal-article","created":{"date-parts":[[2017,2,10]],"date-time":"2017-02-10T09:32:49Z","timestamp":1486719169000},"page":"615-622","source":"Crossref","is-referenced-by-count":48,"title":["Two
