Key result
ECG abnormalities including tachycardia >100 beats/min, P mitrale, and ST segment changes within 72 hours of subarachnoid hemorrhage were significantly associated with death within 7 days.

ECG abnormalities may flag higher-risk SAH; leaves open whether routine monitoring improves outcomes.

Do early ECG abnormalities predict 7-day mortality in patients with subarachnoid hemorrhage?
Early ECG changes reflecting myocardial ischemia or hemodynamic compromise in subarachnoid hemorrhage are significantly associated with increased short-term mortality.
Melin et al. (1983) conducted an observational in Subarachnoid hemorrhage. ECG abnormalities (tachycardia, P mitrale, ST segment changes) vs. Absence of these ECG abnormalities was evaluated on Death within 7 days after bleeding. ECG abnormalities including tachycardia >100 beats/min, P mitrale, and ST segment changes within 72 hours of subarachnoid hemorrhage were significantly associated with death within 7 days.
