| Data ID | 1329 |
| Factor | QT dispersion |
| Description | QT dispersion increased at a rate of 1.1±0.4 ms/year in SCD victims and decreased at a rate of 0.2±0.2 ms/year in controls (P = 0.004). |
| Biomarker | NA |
| Classification | E4 (physiological factor - cardiac function parameter) |

| Application | prognosis |
| Objective | The purpose of the current study was to investigate whether changes over time in electrocardiographic and echocardiographic parameters may enhance prediction of SCD |
| p Value | 0.004 |
| Conclusion | In adults with CHD, QRS duration and ventricular dysfunction progress over time. Progression of QRS duration and the rate of impairment of ventricular function served to identify those at increased risk of SCD. |
