Cardiac involvement manifested as conduction abnormalities, left ventricle mechanical dyssynchrony, dyspnoea, palpitation and postural orthostatic tachycardia syndrome (POTS) are common in long COVID-19. The direct viral damage to the myocardium or immune-mediated inflammation are postulated mechanisms. A woman in her forties presented with a 2-month history of chest pain, functional dyspnoea, palpitation and an episode of syncope after having been home-isolated for mild COVID infection. During clinical workup, a clustering of ECG and echocardiographic abnormalities including left bundle branch block, septal flash, and presystolic wave on spectral Doppler echocardiography, and POTS were detected. The echocardiographic findings together with POTS and persistent dyspnoea indicated the presence of a long COVID-19 state. The prevalence and clinical significance of these finding, as well as the impact on long-term prognosis, should be investigated in future studies.<\/jats:p>","DOI":"10.1136\/bcr-2022-249608","type":"journal-article","created":{"date-parts":[[2022,6,7]],"date-time":"2022-06-07T11:12:15Z","timestamp":1654600335000},"page":"e249608","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":7,"title":["Intermittent left bundle branch block with septal flash and postural orthostatic tachycardia syndrome in a young woman with long COVID-19"],"prefix":"10.1136","volume":"15","author":[{"given":"Vasiliki","family":"Kitsou","sequence":"first","affiliation":[{"name":"Department of Heart Disease, Haukeland University Hospital, Bergen, Norway"},{"name":"Emergency Care Clinic, Haukeland University Hospital, Bergen, Norway"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5647-4297","authenticated-orcid":false,"given":"Bj\u00f8rn","family":"Blomberg","sequence":"additional","affiliation":[{"name":"Department of Clinical Science, University of Bergen, Bergen, Norway"},{"name":"National Advisory Unit for Tropical Infectious Diseases, Department of Medicine, Haukeland University Hospital, Bergen, Norway"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Torbj\u00f8rn","family":"Lunde","sequence":"additional","affiliation":[{"name":"Department of Heart Disease, Haukeland University Hospital, Bergen, Norway"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sahrai","family":"Saeed","sequence":"additional","affiliation":[{"name":"Department of Heart Disease, Haukeland University Hospital, Bergen, Norway"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2022,6,7]]},"reference":[{"key":"2025082708152818000_15.6.e249608.1","doi-asserted-by":"publisher","DOI":"10.1038\/s41591-021-01283-z"},{"key":"2025082708152818000_15.6.e249608.2","doi-asserted-by":"crossref","DOI":"10.1136\/bcr-2020-240095","article-title":"COVID-19 myocarditis and postinfection Bell's palsy","volume":"14","author":"Dahl","year":"2021","journal-title":"BMJ Case Rep"},{"key":"2025082708152818000_15.6.e249608.3","doi-asserted-by":"publisher","DOI":"10.1016\/S1473-3099(21)00703-9\/ATTACHMENT\/31179DEC-CF64-455B-BD13-6EF0045B7DD6\/MMC1.PDF"},{"key":"2025082708152818000_15.6.e249608.4","doi-asserted-by":"crossref","first-page":"1282","DOI":"10.1097\/HJH.0000000000002819","article-title":"Coronavirus disease 2019 and cardiovascular complications: focused clinical review","volume":"39","author":"Saeed","year":"2021","journal-title":"J Hypertens"},{"key":"2025082708152818000_15.6.e249608.5","doi-asserted-by":"crossref","first-page":"25","DOI":"10.1002\/jcu.23101","article-title":"Subclinical myocardial dysfunction in patients following coronavirus disease 2019 infection","volume":"50","author":"Saeed","year":"2022","journal-title":"J Clin Ultrasound"},{"key":"2025082708152818000_15.6.e249608.6","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.m3026"},{"key":"2025082708152818000_15.6.e249608.7","doi-asserted-by":"publisher","DOI":"10.1158\/1055-9965.EPI-20-0606"},{"key":"2025082708152818000_15.6.e249608.8","unstructured":"National Institute for Health and Care Excellence (NICE) .
