ECG may be an inexpensive tool to identify patients at high risk for developing cardiac dysfunction after TBI. This study aimed to examine abnormal ECG findings after isolated TBI and their association with true cardiac dysfunction based on echocardiogram.<\/jats:p>\n<\/jats:sec>\n\nMethods: <\/jats:title>\nThis prospective observational study examined the data from adult patients with isolated and non-operated TBI between 2020 and 2021. Patients aged <18 years and >65 years with and presence of extracranial injuries including orthopedic, chest, cardiac, abdominal, and pelvis, pre-existing cardiac disease, patients who have undergone cardiothoracic surgery, with inotrope drugs, acute hemorrhage, and brain death were excluded from the study.<\/jats:p>\n<\/jats:sec>\n\nResults: <\/jats:title>\nWe examined data from 100 patients with isolated TBI who underwent ECG and echocardiographic evaluation. ECG changes among 53% of mild cases showed a heart rate of 60\u2013100\/min, and 2% of cases showed more than 100\/min. Prolonged pulse rate (PR) interval was observed in 8%, 11%, and 16% of mild, moderate, and severe cases, while no changes in PR interval were observed in 65% of cases. A prolonged QRS pattern was observed in 5%, 7%, and 15% of mild, moderate, and severe cases. A normal QRS complex was observed in 71% of cases. Prolonged QTc was observed in 3%, 10%, and 15% of cases in mild, moderate, and severe cases, respectively.<\/jats:p>\n<\/jats:sec>\n\nConclusion: <\/jats:title>\nRepolarization abnormalities, but not ischemic-like ECG changes, are associated with cardiac dysfunction after isolated TBI. 12-lead ECG may be an inexpensive screening tool to evaluate isolated TBI patients for cardiac dysfunction.<\/jats:p>\n<\/jats:sec>","DOI":"10.25259\/sni_559_2023","type":"journal-article","created":{"date-parts":[[2024,8,23]],"date-time":"2024-08-23T09:28:54Z","timestamp":1724405334000},"page":"296","update-policy":"https:\/\/doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Correlation
