Prehospital ECG monitoring of chest pain patients

Prehospital electrocardiograms (ECGs) have been shown to decrease the time from onset of pain to onset of treatment. They are obtained prior to treatment while the patient is likely to have his/her most intense pain. With paramedics initiating care in the field, patient assessments may be clinically different by the time the patient reaches the hospital. Thus, obtaining an ECG as early as possible during treatment could aid in the access to treatment for the few patients whose ECGs improve with prehospital care. We present a case in which the prehospital presentation was indicative of an acute myocardial infarction (MI), whereas the presentation to the hospital was not as clear-cut. The patient was taken immediately to the catheterization laboratory based on the prehospital findings and was found to have an acute MI that was treated. Laboratory findings indicated that there was a significant improvement in patient outcome based on this early treatment. This case further illustrates the role of a prehospital ECG.
