During unipolar pacing at a deep septal site, a transition in QRS morphology from nonselective to selective pacing (presence of a discrete component on the intracardiac electrogram) was observed, but this was accompanied by concomitant prolongation of the stimulus\u2010to\u2010left ventricular activation time (Stim\u2010LVAT) from 96 to 116\u00a0ms. However, with several additional turns of the lead, a transition from nonselective to selective LBBP with a short and constant Stim\u2010LVAT of 78\u00a0ms was achieved. Our case suggests that a paced QRS morphology transition from nonselective to selective pacing does not always indicate LBBP. Assessment of high\u2010output pacing is mandatory to achieve LBBP.<\/jats:p>","DOI":"10.1111\/pace.14516","type":"journal-article","created":{"date-parts":[[2022,5,22]],"date-time":"2022-05-22T07:29:46Z","timestamp":1653204586000},"page":"1229-1232","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Uncommon output\u2010dependent paced QRS morphology transition during left bundle branch pacing"],"prefix":"10.1111","volume":"45","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2002-9295","authenticated-orcid":false,"given":"Yoji","family":"Iida","sequence":"first","affiliation":[{"name":"Department of Cardiology Kobari General Hospital  Noda Chiba Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nobuyuki","family":"Makishima","sequence":"additional","affiliation":[{"name":"Department of Cardiology Kobari General Hospital  Noda Chiba Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2022,6]]},"reference":[{"key":"e_1_2_5_2_1","doi-asserted-by":"publisher","DOI":"10.1536\/ihj.10.121"},{"key":"e_1_2_5_3_1","first-page":"791","article-title":"Deep septal, distal His bundle pacing for cardiac resynchronization therapy","volume":"6","author":"Vijayaraman P","year":"2020","journal-title":"Heart Rhythm Case Rep"},{"key":"e_1_2_5_4_1","first-page":"30","article-title":"Deep septal, distal His bundle pacing to achieve low and stable capture threshold","volume":"7","author":"Iida Y","year":"2020","journal-title":"Heart Rhythm Case Rep"},{"key":"e_1_2_5_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/jce.15167"},{"key":"e_1_2_5_6_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10840-021-01014-x"},{"key":"e_1_2_5_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jelectrocard.2017.03.004"},{"key":"e_1_2_5_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.hrthm.2019.06.016"},{"key":"e_1_2_5_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacep.2021.02.018"}],"container-title":["Pacing and Clinical Electrophysiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/pace.14516","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1111\/pace.14516","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/pace.14516","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,8,19]],"date-time":"2023-08-19T18:09:59Z","timestamp":1692468599000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/pace.14516"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,6]]},"references-count":8,"journal-issue":{"issue":"10","published-print":{"date-parts":[[2022,10]]}},"alternative-id":["10.1111\/pace.14516"],"URL":"https:\/\/doi.org\/10.1111\/pace.14516","archive":["Portico"],"relation":{},"ISSN":["0147-8389","1540-8159"],"issn-type":[{"value":"0147-8389","type":"print"},{"value":"1540-8159","type":"electronic"}],"subject":[],"published":{"date-parts":[[2022,6]]},"assertion":[{"value":"2022-01-22","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2022-04-29","order":1,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2022-06-01","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
