| Factor | QRS-duration |
| Description | QRS-duration was longer in VTA patients (110ms vs 100; p<0.01). As demonstrated in the upper panel of Figure 2, median QRS duration was higher in VTA patients compared to the control group prior to VTA (110ms (IQR 100 – 150) vs 100ms (IQR 90 –120)). |
| Biomarker | NA |
| Classification | A3 (clinical factor - disease & symptom) |

| Application | prognosis |
| Objective | QRS-duration was longer in VTA patients |
| p Value | 0.001 |
| 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 |
