prolonged dispersion of qt and qtc in thalassemia major patients
thalassemia major patients require repeated transfusions of packed cell and their lysis lead to iron deposition especially in the cardiac walls such as septum and posterior wall, so make thickening and cause cardiac disorders. in this case-control study, our object was to appoint if qt and qtc and te dispersions were predictors of cardiac disorders in thalassemia major patients or not. 34 thala...
متن کاملDispersion of QT and QTc interval in healthy children, and effects of sinus arrhythmia on QT dispersion.
OBJECTIVE To determine the normal values of QT and QTc dispersion and the effects of sinus arrhythmia on QT dispersion in healthy children. PATIENTS AND SETTING The study was carried out in a university hospital on 372 local schoolchildren (200 male, 172 female), aged seven to 18 years. METHODS The QT and preceding RR intervals of at least one sinus beat were measured manually in a range of...

Patients and setting—The study was carried out in a university hospital on 372 local schoolchildren (200 male, 172 female), aged seven to 18 years.

متن کاملThe 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 کاملQT dispersion: an indication of arrhythmia risk in patients with long QT intervals.
Homogeneity of recovery time protects against arrhythmias whereas dispersion of recovery time is arrhythmogenic. A single surface electrocardiographic QT interval gives no information on recovery time dispersion but the difference between the maximum and minimum body surface QT interval may be relevant. This hypothesis was tested by measuring the dispersion of the corrected QT interval (QTc) in...
