Key result
Electrocardiographic abnormalities were not an accurate predictor of myocardial function after subarachnoid haemorrhage, as myocardial dysfunction was more closely related to neurological severity.
Why the study?
Is the ECG an accurate predictor of myocardial function after aneurysmal subarachnoid haemorrhage?
Population
45 patients with intracranial aneurysms (4 excluded due to history of chronic cardiac disease)
Design
Cross-sectional

ECG should not guide myocardial assessment after SAH; leaves open whether neurological severity better informs cardiac evaluation.
Observational (n=45)
Is the ECG an accurate predictor of myocardial function after aneurysmal subarachnoid haemorrhage?
ECG changes are not an accurate predictor of myocardial dysfunction after subarachnoid hemorrhage, as dysfunction correlates more closely with neurological severity.
Davies et al. (1991) conducted an observational in Aneurysmal subarachnoid haemorrhage (n=45). Electrocardiographic (ECG) abnormalities vs. Normal ECG was evaluated on Myocardial dysfunction (wall motion abnormalities on echocardiogram). Electrocardiographic abnormalities were not an accurate predictor of myocardial function after subarachnoid haemorrhage, as myocardial dysfunction was more closely related to neurological severity.
