Why the study?
Do specific catecholamine-linked ECG changes predict poor prognosis (death or cerebral arterial spasm) in patients with subarachnoid haemorrhage?
Population
40 patients with subarachnoid haemorrhage (16 men, mean age 41 years; 24 women, mean age 42 years)
Comparison
Presence of catecholamine-linked ECG changes vs Absence of these specific ECG changes
Design
Cohort

ECG abnormalities were associated with death and vasospasm in SAH; hypothesis-generating and requires prospective validation before guiding care.
Do specific catecholamine-linked ECG changes predict poor prognosis (death or cerebral arterial spasm) in patients with subarachnoid haemorrhage?
Specific ECG abnormalities, such as pathological Q waves and raised S-T segments, are associated with a poor prognosis and the development of cerebral arterial spasm in patients with subarachnoid haemorrhage.
Cruickshank et al. (1974) studied this question.
