Electrocardiographic Findings Associated With Neurological Pathology and Other T-Wave Catastrophes.

An 87-year-old female patient presented with altered mental status. During the routine workup for altered mental status, an electrocardiogram (ECG) was obtained. The ECG showed T-wave morphology known to be consistent with myocardial infarction. Although the ECG is a crucial diagnostic tool to recognize myocardial ischemia and infarction promptly, it must be understood that T-wave abnormalities can represent noncardiac pathology. A case presentation illustrates a unique ECG change whose presence is associated with catastrophic central nervous system diseases that cause increased intracranial pressure.
