Why the study?
Does providing clinical information alter the electrocardiographic diagnosis of acute myocardial infarction by cardiologists?
Population
3 cardiologists interpreting 52 electrocardiograms (ECGs) for acute myocardial infarction
Comparison
Reinterpretation of ECGs with clinical… vs Initial interpretation of the same 52 ECGs…
Design
Other, Initial interpretations were blinded to clinical information
Follow-up
3 weeks (interval between interpretations)

Clinical context can be shared without reducing ECG accuracy for AMI; challenges assumptions of interpretive bias.
Does providing clinical information alter the electrocardiographic diagnosis of acute myocardial infarction by cardiologists?
Providing clinical information to cardiologists did not significantly alter the sensitivity or specificity of their ECG interpretations for acute myocardial infarction, challenging the belief that such information biases diagnostic utility.
Patrick M. Dunn (1990) studied this question.
