Intensive Insulin Treatment and QT-interval

QT Interval and QT Variability

Changes in QT interval before and after hemodialysis

Background: Cardiovascular mortality and morbidity are high in chronic renal failure (CRF) patients. Increased dispersion of QT intervals is known to predispose to ventricular arrhythmias and sudden cardiac death. This study was conducted to assess the effect of hemodialysis (HD) on corrected QT (QTc) intervals and their dispersions (QTd) in chronic hemodialyzed patients. Methods: Fifty-eight p...

Effects of cinacalcet treatment on QT interval in hemodialysis patients

OBJECTIVE Cinacalcet is a calcimimetic drug that acts via calcium-sensing receptors (CaSRs) and increases the sensitivity of CaSRs on the parathyroid gland; thus, it lowers calcium and phosphorus levels as well as parathormone levels. Prolongation of the QT interval is recognized as a risk factor for the development of ventricular arrhythmias and sudden death. Patients with end-stage renal dise...

Dose-Dependent Effects of Methadone on QT interval in Patients under Methadone Maintenance Treatment

Background: The role of methadone in QTc prolongation, Torsades de Pointes (TdP) arrhythmia and sudden cardiac death has been debated. Because of widespread use of methadone in methadone maintenance treatment (MMT) centers, we aimed to study dose-related effects of methadone on QTc prolongation. Methods: In a comparative observational study, 90 patients who were under MMT were evaluated. Patien...
