The patients with DP during AVRT were compared to those without DP.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>DP during AVRT were found only among the left\u2010sided AP (AP\u2010L). Patients with AP\u2010L were divided into Group 1 (n\u00a0\u00a0=\u00a0\u00a017) with DP during AVRT and Group 2 (n\u00a0\u00a0=\u00a0\u00a0108) without DP. Patients in Group 1 had higher incidence of AF in history (47.1%\u00a0vs. 23.1%; P\u00a0\u00a0=\u00a0\u00a00.0376), AF induced during electrophysiological (EP) study (70.6%\u00a0vs. 25%; P\u00a0\u00a0=\u00a0\u00a00.0002). Group\u00a01 had higher heart rate (HR) during AVRT in the EP study (197.2 \u00b1 27\u00a0vs. 175.1 \u00b1 26.3\u00a0bpm; P\u00a0\u00a0=\u00a0\u00a00.0019), but HR of clinical AVRT (208.5 \u00b1 30.8\u00a0vs. 191.6 \u00b1 27.8\u00a0bpm) was not significant different (P\u00a0\u00a0=\u00a0\u00a0ns). Additionally, electrical alternans of QRS amplitude during AVRT in the EP study was more frequent in Group\u00a01 (52.9\u00a0vs. 20.4 %; P\u00a0\u00a0=\u00a0\u00a00.0048).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Patients with DP and AP\u2010L were more prone to develop AF. The presence of DP was associated with faster AVRT rate. The direction of atrium depolarization during AVRT may be different in the presence of DP and probably plays a role in development of AF in this group of patients.<\/jats:p><\/jats:sec>","DOI":"10.1111\/jce.13347","type":"journal-article","created":{"date-parts":[[2017,9,22]],"date-time":"2017-09-22T09:02:43Z","timestamp":1506070963000},"page":"22-29","source":"Crossref","is-referenced-by-count":2,"title":["Double atrial potentials in left\u2010sided accessory pathways are associated with paroxysmal atrial fibrillation"],"prefix":"10.1111","volume":"29","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3228-2586","authenticated-orcid":false,"given":"Krzysztof","family":"B\u0142aszyk","sequence":"first","affiliation":[{"name":"Department of Cardiology University of Medical Sciences  Pozna\u0144 Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adrian","family":"Gwizda\u0142a","sequence":"additional","affiliation":[{"name":"Department of Cardiology University of Medical Sciences  Pozna\u0144 Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Micha\u0142","family":"Wa\u015bniewski","sequence":"additional","affiliation":[{"name":"Department of Cardiology University of Medical Sciences  Pozna\u0144 Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jaros\u0142aw","family":"Hiczkiewicz","sequence":"additional","affiliation":[{"name":"Department of Cardiology Multidisciplinary District's Hospital  Nowa S\u00f3l Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wojciech","family":"Seniuk","sequence":"additional","affiliation":[{"name":"Department of Cardiology University of Medical Sciences  Pozna\u0144 Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Micha\u0142","family":"Michalak","sequence":"additional","affiliation":[{"name":"Department of Statistic &amp; Computers University of Medical Sciences  Pozna\u0144 Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2017,10,11]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.72.1.161"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9149(77)90065-0"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/0735-1097(92)90281-Q"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1053\/euhj.2000.2429"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8159.1992.tb03098.x"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.56.3.409"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.95.2.511"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.91.8.2235"},{"key":"e_1_2_6_10_1","doi-asserted-by":"crossref","first-page":"569","DOI":"10.1016\/S0022-5223(19)36684-X","article-title":"The surgical treatment of atrial fibrillation III.
