ECG abnormalities in SAH indicate low cardiac death risk without predicting mortality; hypothesis-generating and should not yet change practice.
Do electrocardiographic abnormalities consistent with ischemia or myocardial infarction predict cardiac or all-cause mortality in patients with subarachnoid hemorrhage?
In patients with subarachnoid hemorrhage, early ECG abnormalities consistent with ischemia or infarction are associated with a low risk of cardiac death and do not independently predict all-cause mortality.
Zaroff et al. (1999) studied this question.
