Electrocardiographic changes are frequently seen in patients post traumatic brain injury. The prognosis in patients with traumatic brain injury is poor when there is associated abnormal electrocardiographic changes. Though there are many indicators to assess prognosis in traumatic brain injury, ECG is a easily available point of care test which can help understand the outcome in traumatic brain injury patients at an early stage. This study aims to determine the relation of electrocardiographic changes and severity of the head injury and to assess the usefulness of ECG as a prognostic indicator in the outcome of patients with traumatic brain injury.


It is a single centre prospective observational study, conducted between the year 2020 to 2022. Inclusion criteria- all patients with traumatic brain injury diagnosed on computed tomography or magnetic resonance imaging of brain, aged above 18 years and 12 lead ECG taken within 12 hours of arrival to hospital. Patients with history of heart disease, stroke, hypertension, previous documented abnormal ECG were excluded from the study. Initial Glagow coma scale was used to assess the severity of head injury, which was then correlated with the ECG changes. Patients were followed up after 30 days and outcome was assessed by Glasgow Outcome scale. Further, initial ECG changes were correlated with one month outcome.


In our prospective observational study, results showed electrocardiographic changes to be more frequent in patients with severe head injury. The most common ECG abnormality noted were heart rate variability, T wave changes and repolarization abnormalities. These electrocardiographic changes appeared to have significant positive correlation with outcome in patients with traumatic brain injury.


Electrocardiography can be used as a preliminary and simple method to assess the severity of head injury as well as predict the prognosis of patients with traumatic brain injury.
