The most frequent was the ascending ST elevation variant (84%) and lateral ECG locations (74%). The degree of JPE did not differentiate the studied patients. Male sex was associated with the higher risk of ERV (odds ratio [OR] = 2.84; P = 0.003). ERV in inferior ECG leads enhanced the risk of positive tilt testing (OR = 3.57; P = 0.048).

In this population ERV was frequent and associated with positive tilt testing. According to recently described higher risk of SCD among people with ERV, we need further studies and longer follow\u2010up to establish the clinical importance of ERV in patients with reflex syncope<\/jats:italic>.<\/jats:p><\/jats:sec>","DOI":"10.1111\/pace.12072","type":"journal-article","created":{"date-parts":[[2013,1,10]],"date-time":"2013-01-10T20:42:40Z","timestamp":1357850560000},"page":"456-461","source":"Crossref","is-referenced-by-count":10,"title":["Early Repolarization Variant in Syncopal Patients Referred to Tilt Testing"],"prefix":"10.1111","volume":"36","author":[{"given":"ANNA","family":"BARTCZAK","sequence":"first","affiliation":[{"name":"Department of Cardiology, Chair of Cardiology and Cardiac Surgery Medical University of Lodz  Lodz Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"MALGORZATA","family":"LELONEK","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Chair of Cardiology and Cardiac Surgery Medical University of Lodz  Lodz Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2013,1,10]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jelectrocard.2006.05.001"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa0907589"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa071968"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2008.07.010"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9343(03)00355-3"},{"key":"e_1_2_8_7_1","first-page":"4","article-title":"Early repolarization variant: Epidemiological aspects, mechanism, and differential diagnosis","volume":"14","author":"Riera AR","year":"2008","journal-title":"Cardiol J"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1152\/ajpheart.1998.274.6.H2110"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2011.04.003"},{"key":"e_1_2_8_10_1","doi-asserted-by":"publisher","DOI":"10.1093\/eurheartj\/ehp298"},{"key":"e_1_2_8_11_1","first-page":"259","article-title":"Early repolarization electrocardiography pattern with unexplained syncope during training in a young black African non elite athlete: An accidental finding?","volume":"16","author":"Bonny A","year":"2009","journal-title":"Cardiol J"},{"key":"e_1_2_8_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/0002-8703(94)90070-1"},{"key":"e_1_2_8_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.eupc.2004.03.003"},{"key":"e_1_2_8_14_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pmed.1000314"},{"key":"e_1_2_8_15_1","doi-asserted-by":"publisher","DOI":"10.1093\/eurheartj\/ehr264"},{"key":"e_1_2_8_16_1","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCULATIONAHA.110.014068"},{"key":"e_1_2_8_17_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2011.04.022"},{"key":"e_1_2_8_18_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2008.11.011"}],"container-title":["Pacing and Clinical Electrophysiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1111%2Fpace.12072","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/pace.12072","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,11,22]],"date-time":"2023-11-22T07:05:08Z","timestamp":1700636708000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/pace.12072"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2013,1,10]]},"references-count":17,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2013,4]]}},"alternative-id":["10.1111\/pace.12072"],"URL":"https:\/\/doi.org\/10.1111\/pace.12072","archive":["Portico"],"relation":{},"ISSN":["0147-8389","1540-8159"],"issn-type":[{"value":"0147-8389","type":"print"},{"value":"1540-8159","type":"electronic"}],"subject":[],"published":{"date-parts":[[2013,1,10]]}}}
