Aims: Obstructive sleep apnea syndrome (OSAS) is a disorder characterized by recurrent collapse of the upper airway during sleep. OSAS is associated with an increased risk of cardiovascular morbidity and mortality. Tpeak to Trend (Tp-e) interval, the Tp-e interval/QT interval (Tp-e/QT) ratio, and the Tp-e interval/corrected QT interval (Tp-e/QTc) ratio, are associated with ventricular arrhythmias and sudden cardiac death in various disease groups. we aimed to investigate the relationship between changes in the new arrhythmia markers Tp-e interval, Tp-e/QT and Tp-e/QTc ratios in OSAS patients.

Background: The Tp-e/QT (peak to end of T-wave duration/QT interval) ratio is a promising marker of myocardial repolarization and ventricular arrhythmogenesis. Its elevation is associated with sudden cardiac death in different clinical conditions. This study was designed to assess the possible association between increased Tp-e/QT ratio and clinical factors in peritoneal dialysis patients. Materials & methods: We devised a prospective cross-sectional study, which included 107 patients who were divided into groups according to their Tp-e/QT ratio. The association of an increased Tp-e/QT rat

Streszczenie:

Chronic hepatitis B (CHB) is a chronic inflammatory viral disorder. Several studies have suggested that the interval from the peak to the end of the electrocardiographic T wave (Tp-e) may correspond to the transmural dispersion of repolarisation and that increased Tp-e interval and Tp-e/QT ratio are associated with malignant ventricular arrhythmias. Impaired autonomic function has been described in patients with CHB. The aim of this study was to evaluate ventricular repolarisation by using Tp-e interval and Tp-e/QT ratio in patients with CHB, and to assess the relation with inflammation. Fifty

Objective: We aimed to investigate whether there is a change in Tpe interval, Tpe/QT and Tpe/QTc ratios in patients with brain death. Materials and Methods: Fifty brain death patients and 50 age and sex matched healthy controls were included in the study. In addition to routine evaluation, Tp-e interval, Tp-e / QT and Tp-e / QTc ratios were measured in 12-lead electrocardiography. Tp-e was measured in the precordial leads using the Tail method; the time from the peak of the T wave to the point where the wave reached the isoelectric line. Results: White blood cell, aspartate aminotr

Purpose: The purpose of this study is to evaluate ventricular repolarization before, at the first month, and sixth month after Sacubutril/Valsartan, an angiotensin receptor neprilysin inhibitor (ARNI) treatment in heart failure patients with reduced ejection fraction (HFrEF). Materials and Methods: We included 49 patients with HFrEF who switched to ARNI therapy. The 12-lead electrocardiography (ECG) was evaluated before ARNI therapy and also during the first and sixth months of the therapy. We evaluated demographic, clinical, and laboratory parameters, as well as medications and ECG data

Background and Objectives: The autonomic nervous system (ANS) is involved in panic disorders. ANS dysfunction has been shown to be associated with ventricular arrhythmia and increased heterogeneity of ventricular repolarization. However, there remains limited evidence of the relationship between panic disorders and ventricular depolarization markers, including the Tp-e interval and Tp-e/QT ratio. This study aimed to evaluate ventricular repolarization parameters in patients with panic disorder. Materials and Methods: In total, 40 patients with panic disorder, diagnosed using the Diagnostic and

Aims: This study aimed to evaluate Tp-e interval, Tp-e/QT ratio, and Tp-e/QTc ratios, which are new ventricular repolarization (VR) parameters in primary hyperparathyroidism (PHPT) patients, and also investigate the potential effect of parathyroidectomy (PTx) on these parameters. Methods: In total, 27 patients with PHPT who underwent PTx and 25 control subjects were selected for our study. Tp-e interval, Tp-e/QT ratio, and Tp-e/QTc ratios of patients planned for PTx were compared to healthy matched controls. Electrocardiographic parameters measured 6 months after the surgery were also compared

Levothyroxine suppression therapy (LST) can cause some unfavorable effects on the cardiovascular system in patients with differentiated thyroid cancer (DTC). The aim of this study was to evaluate ventricular arrhythmia predictors based on electrocardiography (ECG) in patients with DTC with LST. The ECG parameters including QT, corrected QT (QTc), Tp-e intervals, Tp-e/QT, and Tp-e/QTC ratios of 265 patients with DTC who met the inclusion criteria were compared with 100 controls. No difference was observed in the number of patients with DTC and controls with prolonged and borderline QTc interval

Background: Electronic cigarette (e-cigarette) use is constantly increasing. However, the association between e-cigarette use and ventricular arrhythmia is unknown. Thus, in this study, we aimed to evaluate the markers of ventricular repolarization such as QT interval, corrected QT (QTc), QT dispersion (QTd), peak-to-end interval of the T wave (Tp-e), corrected Tp-e and Tp-e/QT ratios in e-cigarette users. Methods: The study population consisted 36 e-cigarette users and 40 healthy subjects.

The aim of this study is to investigate the changes in QT, QTc, and Tp-e intervals and Tp-e/QT ratio on surface electrocardiogram (ECG) signals during anaesthesia induction using propofol or sevoflurane after preoperative cefuroxime infusion. Some 120 cases of gynaecological patients are randomly divided into propofol (P) and sevoflurane (S) groups (n=60). After cefuroxime (1.5 g) was infused in the two groups of patients, propofol target controlled infusion (TCI) was conducted in the P group for 5 min to realise a plasma concentration of 4 μg/ml while patients in the S group inhaled anaesthes
