It has been determined that myocardial fibrotic scar plays a role in the formation of ventricular arrhythmias by causing structural and electrophysiological changes that cause fragmentation and ventricular late potentials in QRS. Arrhythmia risk is increased in hemodialysis (HD) patients. Regular ECG monitoring and the presence of fQRS can help in the early diagnosis of ventricular arrhythmias in HD patients. The aim of this study is to investigate the relationship between the presence of fQRS and ventricular arrhythmia in HD patients. Methods: In this case-control study, 22 HD patients with fQRS and 72 HD patients without fQRS were compared. The ECG parameters and ECG-holter results of the two groups were compared in terms of the frequency of ventricular arrhythmias by multivariate analysis. A p value <0.05 was considered statistically significant. Results: The compared to ECG-holter data of the both groups, it was statistically detected that the frequency of ventricular premature contraction (VPC) and the number of cases observed in non-susteined ventricular tachycardia (NSVT) increased in the group with fQRS (+) (p <0.001, p:0.01). In addition, it was observed that corrected QT (QTc), dispersion of QTc (QTcd) and transmural dispersion of repolarization (TDR) were extended from ECG parameters in the fQRS (+) group and were statistically significant (p <0.001, p:0.003, p:0.019). Conclusion: The frequency of VPC and NSVT in the fQRS group was significantly higher than in the control group. The presence of fQRS may be used to predict ventricular arrhythmias in HD patients.}, number={2}
