Electrocardiogram alterations in non-traumatic brain injury: a systematic review
Authors' conclusion
Observing ECG alterations carefully after cerebral damage is important in the critical care of these patients as it can expose preexisting myocardial disease and change prognosis.
Study context
- Population
- Patients with acute non-traumatic brain injury (e.g. SAH, intracranial haemorrhage) without known organic heart disease27 original trials
- Outcome
- New-onset ECG alterations in acute non-traumatic brain injury (overview of available data)

Pooled result
As reported in the abstract
New-onset ECG alterations
- Electrocardiographic (ECG) abnormalities associated with acute brain injury could potentially predict poor patient outcomes, possibly heralding neurogenic pulmonary edema (NPE), delayed cerebral ischemia (DCI) and in-hospital death
- Patients with SAH at increased risk of severe ventricular dysrhythmias, which may contribute to high mortality and poor functional outcome at 3 months
Further pooled results
ECG QT dispersion and mortality
- Association less clear: some patients showed poor outcomes, others no relationship with poor outcomes or increased in-hospital mortality
