Metoprolol initially ameliorated symptoms by preventing the heart rate at which LBBB occurred. Over time LBBB presented at slower heart rates and the patient developed recurrent dyspnea during an activity that correlated with the development of LBBB on event monitors and exercise stress testing. A biventricular pacemaker was implanted, and the patient's symptoms remain resolved after a follow\u2010up of over 4 years. More research is needed to define the use of cardiac resynchronization therapy in patients with normal heart function.<\/jats:p>","DOI":"10.1111\/jce.13840","type":"journal-article","created":{"date-parts":[[2019,1,7]],"date-time":"2019-01-07T02:18:24Z","timestamp":1546827504000},"page":"517-519","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Cardiac resynchronization therapy reverses severe dyspnea associated with acceleration\u2010dependent left bundle branch block in a patient with structurally normal heart"],"prefix":"10.1111","volume":"30","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4836-0016","authenticated-orcid":false,"given":"Eric N.","family":"Prystowsky","sequence":"first","affiliation":[{"name":"St Vincent Medical Group, St Vincent Hospital Indianapolis Indiana"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0830-1118","authenticated-orcid":false,"given":"Benzy J.","family":"Padanilam","sequence":"additional","affiliation":[{"name":"St Vincent Medical Group, St Vincent Hospital Indianapolis Indiana"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2019,1,11]]},"reference":[{"key":"e_1_2_4_1_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2018.09.069"},{"key":"e_1_2_4_1_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9149(88)90942-3"},{"key":"e_1_2_4_1_4_1","doi-asserted-by":"publisher","DOI":"10.1590\/S0066-782X2011005000054"},{"key":"e_1_2_4_1_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8167.2005.00268.x"}],"container-title":["Journal of Cardiovascular Electrophysiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1111%2Fjce.13840","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/jce.13840","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1111\/jce.13840","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/jce.13840","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,9,10]],"date-time":"2023-09-10T20:01:59Z","timestamp":1694376119000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/jce.13840"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,1,11]]},"references-count":4,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2019,4]]}},"alternative-id":["10.1111\/jce.13840"],"URL":"https:\/\/doi.org\/10.1111\/jce.13840","archive":["Portico"],"relation":{},"ISSN":["1045-3873","1540-8167"],"issn-type":[{"value":"1045-3873","type":"print"},{"value":"1540-8167","type":"electronic"}],"subject":[],"published":{"date-parts":[[2019,1,11]]},"assertion":[{"value":"2018-12-23","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2018-12-26","order":1,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2019-01-11","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
