Abstract:
The 'spiked helmet sign' (SHS) is an electrocardiographic finding associated with critical illness and a high risk of death; It is likened to ST-elevation, leading to harmful coronary imaging despite lack of apparent myocardial infarction. We describe the case of SHS secondary to high ventilation pressures in the setting of Acute Respiratory Distress Syndrome (ARDS) in a critically ill patient who subsequently developed barotrauma.
