“…Not only are our findings consistent with findings of Gungor et al but also extend their findings. Kuyumcu et al [37] reported a significantly wider fQRSTa [69 (51°)] in SCFP patients compared with those of normal coronary artery patients [46 (36°)]. In contrast to our study, they found a significantly negative correlation (r= -0.496) between TFC and fQRSTa.…”

“… 24 Slow coronary flow was associated with wider f(QRS-T) and prolonged Tp-e interval, Tp-e/QT, and Tpe/QTc ratios compared to those in the general population in a retrospective cohort study. 35 Okutucu et al observed that switching from ramipril to sacubitril/valsartan therapy improved some repolarization by decreasing QTc, Tp-e, and Tp-e/QTc in patients with HFrEF. 36 …”

OBJECTIVES: The relationship between ventricular arrhythmias and major depressive disorder (MDD) has been previously revealed. Recently, frontal QRS-T angle (fQRSTa) and Tp-Te/QT ratio proved to provide more accurate predictive data about ventricular arrhythmias than the measurement of QT, QTc, and QT dispersion. The aim of this study was to determine the effects of MDD on contemporary ventricular arrhythmia indicators. PATIENTS AND METHODS: 57 newly diagnosed MDD patients and 65 healthy subjects were included in the study. Hamilton depression rating scale (HAM-D) and Hamilton Anxiety Rating Scale (HAM-A) were administered and ECG measurements were obtained. Ventricular arrhythmia predisposition was assessed by calculating the Tp-Te/QT ratio in addition to fQRSTa. RESULTS: fQRSTa and Tp-Te/QT ratio values in the MDD group were signifi cantly higher than the control group. Correlation analyses revealed that Tp-Te/QT ratio and fQRSTa signifi cantly correlated with (HAM-D). It was found with linear regression analysis, MDD existence and its severities were independent predictors of fQRSTa and Tp-Te/QT ratio. CONCLUSION: MDD predisposes to ventricular arrhythmia by causing increased fQRSTa and Tp-Te/QT ratio on ECG. Increased fQRSTa and Tp-Te/QT ratio may be useful indicators of dysregulation in the autonomic nervous system and increased risk of ventricular arrhythmias in MDD patients (Tab. 6, Fig. 4, Ref. 38).
