Test characteristics showing the diagnostic accuracy of paramedic ECG interpretation (‘normal’ vs ‘abnormal’) for NSTEMI
| AMI | |
| Sensitivity (95% CI) | 71.3% (60.6% to 80.5%) |
| Specificity (95% CI) | 57.8% (53.8% to 61.8%) |
| NPV (95% CI) | 93.3% (90.8% to 95.1%) |
| PPV (95% CI) | 19.7% (17.2% to 22.4%) |
AMI, acute myocardial infraction; NPV, negative predictive value; NSTEMI, non-ST elevation myocardial infarction; PPV, positive predictive value.
