• In conditions leading to increased intracranial pressure (e.g. subarachnoid hemorrhage, intraparenchymal hemorrhage, traumatic brain injury, mass lesion, or massive edema due to stroke), ECG might show:
“cerebral T waves” (widespread, deep, wide, giant T waves)
markedly prolonged QT intervals
prominent U waves
• In addition, Cushing reflex might cause sinus bradycardia.
