This was only diagnosed after an episode of sustained ventricular tachycardia secondary to myocarditis. In this case report, we focus on the clinical features of this rare autoimmune condition and aim to provide useful tips to both general medical professionals and cardiologists to achieve correct differential diagnosis according to the updated international guidelines and recommendations. Early diagnosis is especially important due to the possible arrhythmogenic complications and the high mortality and morbidity associated with ILD and cardiac abnormalities.<\/jats:p>","DOI":"10.1136\/bcr-2020-234396","type":"journal-article","created":{"date-parts":[[2021,5,26]],"date-time":"2021-05-26T14:35:40Z","timestamp":1622039740000},"page":"e234396","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Rare presentation of antisynthetase syndrome complicated by myocarditis resulting in sustained ventricular tachycardia"],"prefix":"10.1136","volume":"14","author":[{"given":"Mehak","family":"Asad","sequence":"first","affiliation":[{"name":"Department of Cardiology, Stepping Hill Hospital, Stockport, England, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rajavarma","family":"Viswesvaraiah","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Stepping Hill Hospital, Stockport, England, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2021,5,26]]},"reference":[{"key":"2025082711294805000_14.5.e234396.1","doi-asserted-by":"publisher","DOI":"10.1093\/rheumatology\/keu404"},{"key":"2025082711294805000_14.5.e234396.2","doi-asserted-by":"crossref","DOI":"10.1136\/bcr-2019-231006","article-title":"Jo1-antisynthetase syndrome and severe interstitial lung disease with organising pneumonia on histopathology with favourable outcome on early combined treatment with corticosteroids, mycophenolate mofetil and rituximab","volume":"12","author":"R\u00fcegg","year":"2019","journal-title":"BMJ Case Rep"},{"key":"2025082711294805000_14.5.e234396.3","doi-asserted-by":"crossref","unstructured":"De Langhe E , Lenaerts J , Bossuyt X , et al .
