| Factor | moderate/severe non-systemic ventricular dysfunction |
| Description | Multiple conditional logistic regression demonstrated more fQRS (OR 2.9, 95% CI 1.5–5.8; p=0.002), non-systemic ventricular dysfunction (OR 5.1, 95% CI 2.1–12.4; p<0.001) and more prolonged QRS complexes (OR 2.8, 95% CI 1.3–6.2; p=0.011) in VTA patients. |
| Biomarker | NA |
| Classification | A3 (clinical factor - disease & symptom) |
| Association | |
|---|---|
| Application | prognosis and risk assessment |
| Objective | non-systemic ventricular dysfunction |
| p Value | <0.001 |
| OR | >5.0 |
| Conclusion | the presence of fQRS on ECG may be a useful tool in daily clinical practice to identify patients at risk for developing VTA in patients with CHD, in addition to known predictors of VTA |
