The role of prehospital electrocardiograms in the recognition of ST-segment elevation myocardial infarctions and reperfusion times.

Background: Clinical outcomes in ST-segment elevation myocardial infarction (STEMI) are related to reperfusion times. Given the benefit of early recognition of STEMI and resulting ability to decrease reperfusion times and improve mortality, current prehospital recommendations are to obtain electrocardiograms (ECGs) in patients with concern for acute coronary syndrome.

Objectives: We sought to determine the effect of wireless transmission of prehospital ECGs on STEMI recognition and reperfusion times.
