Abstract:
Electrocardiographic changes in neurovascular disease are not rare. Patients with subarachnoid hemorrhage have electrocardiographic (ECG) abnormalities that may mimic ischemic heart disease and acute myocardial infarction. Outflow of catecholamines in the early stage of subarachnoid hemorrhage contributes to elevated blood pressure in most patients. Hypotension is a rare presentation in subarachnoid hemorrhage. We report a case of subarachnoid hemorrhage with transient ST elevation and intractable shock simulating acute myocardial infarction, and review the mechanism of ECG changes in subarachnoid hemorrhage.
