At first glance this ECG shows diffused ST elevation, but this isnt MI nor pericarditis. This ECG was taken from a previously healthy 18-year old girl with severe traumatic brain injury and massively raised intracranial pressure (30-40 mmHg). There is widespread ST elevation with a pericarditis-like morphology and no reciprocal change (except in aVR and V1). She had no cardiac injury / abnormality to explain the ST elevation. The ST segments normalised as the intracranial pressure came under control (following treatment with thiopentone and hypertonic saline). So raised ICP can cause ECG modifications so dont forget that π @medicalcortex
