Key result
Paramedic prehospital ECG interpretation outperforms computer assistance for STEMI detection with ~96% sensitivity.
Why the study?
Does paramedic or computer-assisted interpretation of prehospital ECGs accurately identify ST-Segment Elevation Myocardial Infarction?
Meta-Analysis (n=49,131)
Does paramedic or computer-assisted interpretation of prehospital ECGs accurately identify ST-Segment Elevation Myocardial Infarction?
Effect estimate: Pooled sensitivity 95.5% (95% CI 82.5-99.0)
Paramedic interpretation of prehospital ECGs for STEMI has favorable diagnostic accuracy, whereas computer-assisted interpretation has high specificity but low sensitivity.
Prioritizes paramedic over computer-assisted prehospital ECG interpretation for STEMI activation; reinforces meta-analytic support for human-led triage protocols.
This meta-analysis suggests that the diagnostic accuracy of paramedic prehospital ECG interpretations is favorable, with high pooled sensitivity and specificity, with an acceptable estimated number of false positives and false negatives. Computer-assisted ECG interpretation showed high pooled specificity with an acceptable estimated number of false positives, whereas the pooled sensitivity was relatively low.

Tanaka et al. (2022) conducted a meta-analysis in ST-segment elevation myocardial infarction (STEMI) (n=49,131). Prehospital ECG interpretation by paramedics or computers vs. 12-lead ECG or clinical diagnosis of STEMI by a physician was evaluated on Diagnostic accuracy (pooled sensitivity) of paramedic prehospital ECG interpretation (Pooled sensitivity 95.5%, 95% CI 82.5-99.0). Paramedic prehospital ECG interpretation for STEMI demonstrated a pooled sensitivity of 95.5% and specificity of 95.8%, while computer-assisted interpretation showed a sensitivity of 85.4% and specificity of 95.4%.
