Bidirectional ventricular tachycardia (BVT) is a rare but potentially fatal form of polymorphic tachycardia associated with elevated sympathetic tone.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case summary<\/jats:title>\n                    <jats:p>A 27-year-old Caucasian woman was admitted to the intensive care unit with cardiogenic shock. The electrocardiogram showed BVT, and the transthoracic echocardiogram showed a dilated left ventricle with severe systolic dysfunction. Computed tomography revealed an adrenal mass with haemorrhage, which was confirmed by abdominal magnetic resonance imaging. The patient underwent a laparoscopic right adrenalectomy after pre-operative preparation with alpha\u2013beta blockade, with subsequent histopathological confirmation of the diagnosis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>The acute presentation of haemorrhagic necrosis of a pheochromocytoma is a rare and potentially lethal condition. Its diagnosis can be challenging, especially in cases with atypical manifestations. However, the presence of BVT might serve as a crucial guide for its identification. Early recognition of this condition is essential, as it significantly impacts the patient's prognosis.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1093\/ehjcr\/ytaf664","type":"journal-article","created":{"date-parts":[[2025,12,19]],"date-time":"2025-12-19T13:00:35Z","timestamp":1766149235000},"source":"Crossref","is-referenced-by-count":1,"title":["Bidirectional ventricular tachycardia and cardiogenic shock caused by acute haemorrhagic necrosis of pheochromocytoma: a case report"],"prefix":"10.1093","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-6478-262X","authenticated-orcid":false,"given":"Alejandro Manuel","family":"L\u00f3pez-Pena","sequence":"first","affiliation":[{"name":"Cardiology Department, Hospital Universitario Lucus Augusti , 27003 Lugo ,","place":["Spain"]},{"name":"CardioHULA Research Group, Fundaci\u00f3n Instituto de Investigaci\u00f3n Sanitaria de Santiago de Compostela FIDIS , 27003 Lugo ,","place":["Spain"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2005-6322","authenticated-orcid":false,"given":"Charigan","family":"Abou Jokh-Casas","sequence":"additional","affiliation":[{"name":"Cardiology Department, Hospital Universitario Lucus Augusti , 27003 Lugo ,","place":["Spain"]},{"name":"CardioHULA Research Group, Fundaci\u00f3n Instituto de Investigaci\u00f3n Sanitaria de Santiago de Compostela FIDIS , 27003 Lugo ,","place":["Spain"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jorge","family":"Armesto-Rivas","sequence":"additional","affiliation":[{"name":"Cardiology Department, Hospital Universitario Lucus Augusti , 27003 Lugo ,","place":["Spain"]},{"name":"CardioHULA Research Group, Fundaci\u00f3n Instituto de Investigaci\u00f3n Sanitaria de Santiago de Compostela FIDIS , 27003 Lugo ,","place":["Spain"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-3885-7072","authenticated-orcid":false,"given":"Gonzalo","family":"De Urbano-Seara","sequence":"additional","affiliation":[{"name":"Cardiology Department, Hospital Universitario Lucus Augusti , 27003 Lugo ,","place":["Spain"]},{"name":"CardioHULA Research Group, Fundaci\u00f3n Instituto de Investigaci\u00f3n Sanitaria de Santiago de Compostela FIDIS , 27003 Lugo ,","place":["Spain"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4483-9778","authenticated-orcid":false,"given":"Carlos","family":"Gonz\u00e1lez-Juanatey","sequence":"additional","affiliation":[{"name":"Cardiology Department, Hospital Universitario Lucus Augusti , 27003 Lugo ,","place":["Spain"]},{"name":"CardioHULA Research Group, Fundaci\u00f3n Instituto de Investigaci\u00f3n Sanitaria de Santiago de Compostela FIDIS , 27003 Lugo ,","place":["Spain"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2025,12,22]]},"reference":[{"key":"2026011903564779400_ytaf664-B1","doi-asserted-by":"crossref","first-page":"665","DOI":"10.1016\/S0140-6736(05)67139-5","article-title":"Phaeochromocytoma","volume":"366","author":"Lenders","year":"2005","journal-title":"Lancet"},{"key":"2026011903564779400_ytaf664-B2","doi-asserted-by":"crossref","first-page":"7","DOI":"10.1016\/j.jelectrocard.2019.09.023","article-title":"Pheochromocytoma -
