Cerebral T Waves

Characteristic ECG Abnormalities with Raised Intracranial Pressure Widespread giant T-wave inversions (“cerebral T waves”) QT prolongation Bradycardia (the Cushing reflex – indicates imminent brainstem herniation) Other possible ECG changes that may be seen: ST segment elevation / depression — this may mimic myocardial ischaemia or pericarditis Increased U wave amplitude Other rhythm disturbances: sinus tachycardia, junctional rhythms, premature ventricular contractions, atrial fibrillation In some cases, these ECG abnormalities may be associated with echocardiographic evidence of regional ventricular wall motion abnormality (so-called “neurogenic stunned myocardium”). ...
