Key result
Emergency physician interpretation of ST-segment elevation ECGs was correct in 94.9% of cases, with appropriate thrombolytic administration in 83%, though certain syndromes were often misdiagnosed.
Why the study?
Can emergency physicians correctly identify the cause of ST-segment elevation on ECG and appropriately administer thrombolytic therapy?
Population
458 emergency physicians (193 postgraduate year 2-3, 265 attending)

Supports emergency ECG interpretation competency; leaves open whether targeted training reduces misdiagnosis of specific ST-elevation syndromes.

Can emergency physicians correctly identify the cause of ST-segment elevation on ECG and appropriately administer thrombolytic therapy?
Emergency physicians generally interpret ST-segment elevation accurately, but specific syndromes like left ventricular aneurysm and benign early repolarization are frequently misdiagnosed, leading to inappropriate thrombolytic decisions.
Brady et al. (2001) conducted a cross-sectional in ST-segment elevation interpretation (n=458). ECG interpretation was evaluated on Overall rate of correct interpretation of the study ECGs. Emergency physician interpretation of ST-segment elevation ECGs was correct in 94.9% of cases, with appropriate thrombolytic administration in 83%, though certain syndromes were often misdiagnosed.
