Utility of the ECG in diagnosing left ventricular systolic dysfunction by ‘eyeball’ assessment.
| Sensitivity (95% CI) | Specificity (95% CI) | PPV (95% CI) | NPV (95% CI) |
|---|---|---|---|
| 0.82 (0.74 to 0.89) | 0.58 (0.51 to 0.65) | 0.55 (0.47 to 0.62) | 0.83 (0.77 to 0.90) |
PPV = positive predictive value. NPV = negative predictive value.
