| Factor | Percent of fQRS (fragment QRS) |
| Description | Furthermore, fQRS was more frequently observed in VTA patients in the last ECG prior to VTA (N=73 (53%) vs N=67 (31%); (p<0.001); especially in patients with sustained VTA (64%). Multiple conditional logistic regression demonstrated more fQRS (OR 2.9, 95% CI 1.5–5.8; p=0.002) in VTA patients. |
| Biomarker | NA |

| Application | prognosis and risk assessment |
| Objective | fQRS was more frequently observed in VTA patients in the last ECG prior to VTA, especially in patients with sustained VTA |
| p Value | <0.01 |
| OR | >2.5 |
| 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 |
