The impact of chronic hemodialysis on QT dispersion corrected QTdispersion and maximum QT-dispersion
Introduction: Sudden cardiac death is common in patients on hemodialysis and may occur in the immediate postdialysis period when ventricular premature complexes are common. QT dispersion reflecting hetovogelity in ventricle repolarization has been used for predicting patients with risk of malignant arrhythmia and sudden death. The purpose of the study was to assess the effect of hemodialysis on...
متن کاملAssociation between maximal oxygen uptake and the heart rate corrected-QT interval in postmenopausal overweight women.
BACKGROUND Increased aerobic capacity can reduce the incidence of cardiovascular disease and the mortality rate. On the other hand, a prolonged heart rate corrected-QT (QTc) interval is associated with an increased risk of arrhythmias, cardiac sudden death and coronary artery disease. AIMS The association of the aerobic capacity and coronary risk factors with QTc interval was investigated in ...
متن کاملThe QT and corrected QT interval in recovery after exercise in children.
BACKGROUND Prolongation of the QT interval after exercise can be used to help diagnose long-QT syndrome, especially when the resting QT interval is borderline. The aim of this study was to determine the normal ranges for QT and corrected QT in the recovery phase after exercise in children. METHODS AND RESULTS Ninety-four volunteer boys and girls aged 8 to < 17 years without any history of hea...
متن کامل[Corrected QT interval and corrected QT interval dispersion is worthwhile when interpreted with other repolarization measurements].
We read the article entitled ‘‘The effect of esmolol on corrected-QT interval, corrected-QT interval dispersion changes seen during anesthesia induction in hypertensive patients taking an angiotensin-converting enzyme inhibitor’’ by Ceker et al. with interest.1 The authors investigated the effects of esmolol on the hemodynamic, correctedQT (QTc) interval and corrected-QT interval dispersion (QT...
متن کاملQT Interval: Correction for Heart Rate
There are several empirically based proposals in the literature for adjusting QT intervals for heart rate. Two widely used correction formulas are Bazett’s and Fridericia’s. This study examines the general formulation of heart rate correction of QT intervals, and several of the existing adjustments are used with this approach. Simple correction formulas for both populations and individuals have...
