Pre-hospital electrocardiography

An ambulance has been called to a male complaining of chest pain. On arrival you find the male is pale, sweaty, clammy and feeling nauseous. Once an electrocardiograph (ECG) has been undertaken there is ST-segment elevation above 2mms in the anterior leads. The patient is treated for an ST segment myocardial infarction (STEMI) and taken to the local cardiac catheter lab.
