Summary of multivariate analysis for identifying variables independently associated with death among patients who had a second ECG during hospitalization, n = 169.
| Variables | OR | 95% CI | P value |
|---|---|---|---|
| Model A | |||
| Age (per 10 years) | 1.76 | 1.26–2.55 | 0.002 |
| Modified ECG (as compared to baseline) | 3.56 | 1.60–8.34 | 0.002 |
| Model B | |||
| Age (per 10 years) | 1.81 | 1.41–2.29 | < 0.001 |
| New negative T wave | 2.72 | 1.14–6.54 | 0.02 |
| New S1Q3 pattern | 13.23 | 1.49–286.56 | 0.03 |
| New supraventricular arrhythmia | 3.80 | 1.11–13.35 | 0.03 |
ECG, electrocardiogram; CI, confidence interval.
Model 1 was adjusted for age (per 10 years), and modified ECG.
Model 2 was adjusted for age (per 10 years), new negative T wave, new S1Q3 pattern, and new supraventricular arrhythmia.
